How not to drive a 300SL Gullwing, 'Manthey' MX-5 & the next Nissan GT-R | Episode 48

Manthey is a motorsport-focused Porsche tuning brand known for developing track-oriented upgrades. In this episode, “Mantai kit” refers to their package of changes for the Porsche 911 GT3. The host emphasizes that Manthey’s approach here is to improve handling and aero rather than reworking the core engine/gearbox.

Powertrain is the car’s main mechanical drive system—typically the engine plus transmission and related components that send power to the wheels. When the host says the kit “doesn’t touch the powertrain,” they mean it avoids changing the engine/gearbox calibration or hardware. That makes the kit’s impact mainly about how the car grips and how it stays stable at speed.

Aero (aerodynamics) refers to how the car’s shape and add-on parts manage airflow. On track cars, aero is often used to generate downforce, which increases grip at speed without relying on more engine power. The host’s point is that this Manthey kit focuses on aerodynamic changes alongside suspension.

Suspension is the system that connects the wheels to the car and controls how the car moves over bumps and during cornering. Track-focused suspension changes can improve tire contact, reduce body movement, and make the car more predictable under braking and cornering. Here, the host says the kit is “all about the suspension and the aero,” meaning these are the main performance levers.

Lightweight wheels reduce unsprung mass (weight not supported by the suspension springs). Lower unsprung mass helps the suspension respond faster to road and track surface changes, improving grip and ride control. In performance kits, wheel weight is a common target because it affects how quickly the tires can stay working effectively.

Carbon trim refers to interior or exterior pieces made from carbon fiber composite. Carbon fiber is valued in performance applications for its high stiffness-to-weight ratio, allowing parts to be lighter and sometimes more rigid than conventional materials. In this segment, it’s mentioned as part of Manthey’s “rolling catalog of parts.”

Dampers (shock absorbers) control how quickly the suspension compresses and rebounds. “Four-way adjustable” typically means you can set multiple damping parameters (often compression and rebound, sometimes in separate ranges), letting you dial in grip and stability as conditions change.

Turning vanes are shaped aerodynamic surfaces that “direct” airflow, often used to manage how air moves under the car. In underbody aero, they help feed the diffuser and keep the flow organized so the car can generate downforce efficiently.

A diffuser is an underbody aerodynamic device that expands airflow as it exits the car’s underside. That expansion creates lower pressure under the car, which increases downforce and improves high-speed stability.

Running over curbs is a track-driving reality that can damage low-slung underbody aero parts. This segment implies the materials (plastic vs carbon) are chosen to tolerate curb strikes and track-day abuse.

Downforce is the downward aerodynamic force that pushes a car toward the road at speed. More downforce generally improves grip and stability, especially in corners, but it can also increase drag depending on how it’s generated.

Drag is the aerodynamic resistance that slows a car down as it moves through air. The hosts are saying the car gained downforce without increasing drag, which is a key efficiency goal in aero development.

Homologation is the process of certifying a car configuration so it’s legally allowed for road use or for a specific racing category. In this context, they’re talking about keeping the aero/parts within the approved rules so the car can be used as intended.

Manthey (spoken here as “Manto”) is a Porsche-focused motorsport and tuning outfit known for developing track-oriented Porsche packages. The hosts credit Manthey’s approach to improving aerodynamic performance without adding weight.

A factory warranty is coverage provided by the manufacturer for repairs within a defined period and terms. Here, the hosts emphasize that the car’s parts are official and supported, so dealer service should be straightforward.

A “two-part test” here means they evaluate the car in two different environments—road and track—to understand how aero and drivability behave under real-world and high-load conditions. This helps separate everyday comfort/behavior from performance limits.

“Track-oriented” describes a car setup or model focus tuned for circuit driving—typically prioritizing grip, braking stability, and suspension/aero behavior over everyday comfort. In this context, it explains why the hosts were initially worried about road drivability.

Thruxton Circuit is a UK race track used to evaluate how changes to suspension and aero settings affect real driving behavior. Here, it’s the reference point for comparing damper settings between road use and circuit use.

The Porsche 911 GT3 RS is a track-focused version of the 911, built around delivering high grip and predictable handling with a more aggressive aero package. In this segment, the hosts compare how it feels on the road versus a track-oriented setup, highlighting that it can still be usable outside the circuit.

A rear wing is an aerodynamic device mounted at the back that generates downforce by redirecting airflow. On track-oriented cars, it’s often larger and more adjustable, helping keep the car stable and planted through corners.

Dampers (shock absorbers) control how quickly the suspension moves after hitting bumps. When the host says you can hear the rear dampers working over speed bumps, they’re describing suspension damping action—how the car manages vertical motion at the rear.

Apple CarPlay is a smartphone integration system that mirrors compatible iPhone apps onto the car’s infotainment screen. The host mentions it to highlight that even a track-oriented car can still have modern daily-driver tech.

“Fifth gear everywhere” is a shorthand for how the track’s speed profile keeps the car in a relatively high gear for most corners. That usually means less frequent downshifting and a stronger emphasis on maintaining speed through the turns.

Braided brake lines are hoses reinforced with a braided material to reduce brake-fluid “sponginess.” That makes pedal feel firmer and can improve consistency under hard track braking. The hosts connect this change to better braking performance and stability during turning.

Front dampers are the shock absorbers that control how the front of the car moves over bumps and during steering. Stiffening them can reduce unwanted front-end “fall over” as the car turns in, improving stability and grip consistency. Here, the speaker says the front dampers were stiffened by 20% to help turn-in behavior.

Brake pads are the friction material that clamps onto the brake disc to create stopping force. On track cars, pad compounds are often tailored for specific rotor types (like ceramic discs) and for heat range. The hosts mention an “extra option” for their own brake pads that only work with ceramic discs, emphasizing that pad choice is part of the overall braking system design.

Ceramic brake discs (ceramic rotors) are high-performance rotors made from ceramic materials rather than traditional cast iron. They can offer strong fade resistance for repeated hard braking, which matters on track. The hosts note that certain brake pads only work with ceramic discs, highlighting how brake pad/rotor compatibility affects performance.

“Brake fade” is when braking performance drops after repeated hard use, usually because the brake system overheats. The hosts are saying these brakes didn’t fade, meaning they stayed consistent lap after lap and in demanding conditions.

“Cup 2” refers to Michelin’s Pilot Sport Cup 2 track-focused tire line, known for high grip and strong performance when hot. The hosts are linking the tire choice to braking feel and wet traction, implying the tire compound and construction help the car stay consistent.

“Cup 2 R” is a more track-oriented variant within Michelin’s Cup 2 family, typically aimed at even higher grip and faster warm-up for motorsport-style driving. The discussion suggests this tire option (or an equivalent) is part of what makes the car’s braking and wet-road feel impressive.

Bridgestone is a tire brand referenced as an alternative source for equivalent track-focused tires. The point is that the performance characteristics they’re praising can be achieved with different brands, not just one specific model.

Pirelli is a tire brand mentioned as another option for equivalent track-oriented tires. The hosts are framing tire choice as a key part of the car’s consistent feel, regardless of which brand you choose.

Dunlop is a tire brand mentioned as an alternative to Michelin’s Cup 2/R lineup. The hosts are saying you can choose comparable track-oriented tires from other manufacturers depending on availability and preference.

This is the all-in cost estimate for buying a base car with no options and then adding the discussed kit. It’s a “total cost of ownership” style calculation, but specifically about the purchase price plus the kit and fitting.

A roll cage is a reinforced metal frame installed inside the cabin to protect occupants in a crash. It also stiffens the chassis, which can improve handling response—especially when a car is being used for track driving.

Manthey (often associated with Porsche motorsport and track preparation) is referenced here as a track-oriented program/event. In this segment, “Manthey” is tied to using specific cars at the Nürburgring, implying a higher level of preparation and performance focus than casual driving.

Carbon fiber discs here refers to wheel-mounted or wheel-cover style pieces made from carbon fiber, used to create a distinctive motorsport look. In the context of the segment, they’re described as especially eye-catching and reminiscent of race-car styling.

The Porsche 935 is a race-bred evolution of the 911, built for endurance and competition. It’s known for its aggressive styling and motorsport hardware, which is why it’s described as “eye-catching.” In your excerpt, it’s used as a comparison for how certain cars look and stand out.

An engine swap is when you remove one engine from a car and install a different engine from another vehicle (or a different model/variant). It’s a common modification approach because it can dramatically change power, feel, and how the car behaves.

The Mazda MX-5 is a lightweight, front-engine, rear-wheel-drive roadster known for its simple, balanced driving feel. In this segment, the hosts compare an MX-5-based build to a “big engine in it,” which is the key idea behind how Manthey-style tuning can change the car’s character while keeping the proportions.

“Stage” levels are aftermarket tuning tiers that typically correspond to how much hardware and calibration work has been done (for example, intake/exhaust upgrades and engine management changes). “Stage two and a half” implies a build between common stage-two and stage-three levels, aiming for a specific balance rather than the maximum possible setup.

“Second-gen” means the second generation of a model line, where the car’s design and engineering are updated compared to the first generation. Here, it’s used to identify which MX-5 generation the speaker is talking about before discussing its specific tuning package.

A “3.0-litre V6” is an engine with six cylinders arranged in a V shape, with a total displacement of 3.0 liters. In this segment, the hosts connect that engine choice to the car’s power output and explain why it’s notable despite being used in other brands.

Jaguar is referenced as the brand that used this V6 engine in “stodgy-looking” cars, which is why the engine is described as overlooked. The point is that the same engine can have different reputations depending on which brand and model it’s installed in.

“Durotep-based” refers to the engine’s underlying design family or architecture that the speaker says the 3.0-litre V6 is derived from. This matters because it frames the engine as a known platform that later got adapted across different manufacturers and applications.

Ford is mentioned as the next company to take the engine after Porsche sold it. This highlights how major manufacturers sometimes share or license engine designs, leading to the same core powerplant appearing in different marque applications.

Cylinder head work refers to modifications to the cylinder head, such as porting, valve changes, or combustion-chamber refinements. Because the cylinder head governs airflow and how efficiently fuel burns, it’s a key area for performance tuning.

Cosworth is described as doing cylinder head work on the engine after Ford took it on. Cylinder head work is a common performance path because it affects airflow and combustion efficiency, which can improve power and drivability.

A flat-six is an engine layout where six cylinders sit horizontally in two banks of three, opposed to each other. This design can help balance vibration and often gives a distinctive sound and smoothness compared with other layouts.

Induction noise is the sound produced as air is drawn into the engine—often amplified by intake design, throttle response, and sometimes aftermarket intake/exhaust setups. It’s a big part of why some engines feel “alive” even when you’re not pushing hard.

Saying the engine is “a cylinder shorter” points to a physically shorter engine package—typically achieved by changing engine design so the overall length is reduced. A shorter engine can improve packaging, weight distribution, and how the car fits in the chassis.

Cam covers (valve cover/cylinder head covers) protect the top of the engine and help seal oil inside. Using carbon-fiber cam covers is mostly about weight reduction and a distinctive look, and it’s a common “show-and-go” style modification on enthusiast cars.

The Opel Manta is a sporty coupe from Opel that’s often remembered for its bold styling and enthusiast following. In your excerpt, it’s used as a comparison point—specifically noting a “freakishly” chosen characteristic—suggesting the conversation is about how one car’s look or setup contrasts with another. That makes it relevant as a reference for distinctive appearance or personality.

“Unrestored, unrusty” describes a car that hasn’t been cosmetically rebuilt and doesn’t have significant corrosion. For older enthusiast cars, that matters because rust repair is expensive and can hide underlying structural issues.

Aftermarket tuning means replacing or adding non-factory parts (like intake, exhaust, ECU software, suspension, and brakes) to change how a car performs. It’s often used to increase power, sharpen throttle response, and improve handling beyond what the stock car delivers.

Drivetrain is the set of components that deliver power from the engine to the wheels, including the transmission and driveshafts. When tuners keep the same drivetrain, they’re betting it can handle the added engine output.

Torque is the engine’s twisting force that strongly influences how hard the car accelerates, especially at lower RPMs. The speaker contrasts the car’s torque level with how it feels, noting it isn’t “massively torquey,” so it isn’t overwhelmed.

RPM (revolutions per minute) measures how fast the engine spins. Revving to around 8,000 RPM indicates the engine is designed to make power higher in the rev range, which can create a more “eager” sports-car feel.

Rocketeer is mentioned as a company that supplies finished cars and also sells conversion kits. In this segment, they’re described as doing engine conversions and potentially offering turnkey builds where they source and restore a base car.

Engine-converted cars are vehicles that have been modified so they use a different engine than they originally came with. The segment frames Rocketeer’s experience as having supplied many of these conversions, either as completed cars or as kits.

Conversion kits are packaged parts and components intended to change a car’s configuration—here, to install a different engine. They typically include the hardware needed for mounting and integration, and may be sold alongside guidance for the conversion process.

An engine transplant is the process of removing one engine from a car and installing a different engine. It usually requires custom fabrication and engineering work so the new engine fits, mounts correctly, and can be integrated with the car’s systems.

Subframe changes refer to modifying the car’s structural mounting framework that the engine and drivetrain components attach to. For an engine conversion, the subframe often needs alterations so the new engine’s mounting points line up and the car’s geometry and strength remain correct.

“Blast the shell” refers to abrasive blasting of the car’s bare body shell to strip old paint and coatings. It’s commonly used before restoration and repainting so the new paint can adhere properly and rust/imperfections can be addressed.

The Ford Capri is a sporty coupe that was produced in multiple generations, often associated with affordable performance and styling. In the context you shared, it’s brought up in relation to paint jobs and appearance details. That makes it a useful reference when discussing how certain cars look after customization.

In enthusiast circles, a “project” usually means a custom or restoration build where the shop does significant work beyond routine maintenance. Here, the speaker discusses the minimum price for a project and how the shop chooses what kind of base cars to work on.

A donor car is the original vehicle you buy and then use as the parts/source platform for a build. In this case, the speaker clarifies that the quoted project price doesn’t include the donor car, and you either provide it or the shop sources one for you.

“Tired cars” is enthusiast shorthand for vehicles that are worn out or not in great condition—often with higher mileage, age-related wear, or mechanical issues. The speaker says the business tries to choose these tired cars to work on instead of pristine ones, likely because they’re cheaper and still workable as donor bases.

The Porsche 964 Carrera II is the 911 generation from the late 1980s/early 1990s, and “Carrera II” specifically denotes rear-wheel drive. It’s a popular enthusiast baseline because it sits in the classic 911 shape while introducing more modern 964-era refinements.

“Man-hours” is a measure of labor time—how many hours of work it takes one person (or the equivalent total across multiple people). In restoration and custom builds, man-hours are a major driver of cost because skilled work is expensive.

The Bentley Continental GTS is a grand tourer focused on high-speed comfort and performance, and in this discussion it’s specifically framed as a “performance hybrid.” The host contrasts its power output and positioning versus the faster Continental Speed, while also noting it shares chassis technology with that higher-spec model.

A “performance hybrid” is a hybrid powertrain tuned to deliver stronger acceleration and higher power output than a typical efficiency-focused hybrid. In this discussion, it’s used to describe how the Bentley Continental GTS’s hybrid system is calibrated for driving feel and speed rather than just fuel economy.

The Aston Martin Vantage S is a performance-focused version of the Vantage, aimed at delivering sharper steering and more driver feedback than a more grand-touring setup. In this segment, the hosts compare its feel to other Aston models, highlighting how steering weight and response can differ between trims.

The Aston Martin DBX707S is a high-output, sport-tuned variant of the DBX SUV line. The segment frames it as already near the limit of what Aston can extract from that platform, compared with the newer DB12’s wider range for chassis and software changes.

The Aston Martin DB12 is a grand tourer (GT) that’s being discussed here in terms of chassis tuning and steering feel. The hosts describe how Aston made “nose to toe” chassis tweaks and used software changes—then removed a damper-related setup that was intended to create a self-centering steering effect.

“E-pass” here refers to an electronic power-assist system used to control steering effort. Changing it can alter steering weight and the way the car reacts to driver inputs, which is why it’s mentioned alongside steering feel and software updates.

The self-centering effect is the tendency of a steering system to return the wheel toward center after you turn. It’s influenced by suspension geometry, steering assist, and damping components, and it strongly affects how “natural” steering feels at speed and during corner exit.

In performance driving, steering “communication” refers to how clearly the car relays information about grip and load through the steering wheel. Better communication usually comes from chassis setup and tire behavior working together, so the driver can predict what the car will do next.

When the hosts say the tires are “doing more work,” they mean the tires are being used more effectively to generate grip and manage the car’s forces. That often comes from better suspension tuning and tire contact, so the car feels more communicative rather than just “grip, grip, grip.”

A tire’s “footprint” is the portion of the tread that contacts the road. More effective contact (often from suspension geometry and compliance) can improve grip consistency and steering feel because the tire can work over a larger, more stable contact patch.

Body control is how effectively a car manages its body motions—like roll, pitch, and squat—especially during braking, acceleration, and cornering. Better body control usually means the suspension keeps the tires working consistently, improving grip and steering feel.

The Aston Martin DBX S is a higher-performance version of Aston Martin’s DBX luxury SUV. Here, it’s referenced alongside the Vantage S to illustrate that Aston Martin’s improvements came through step-by-step updates across multiple models.

GT mode is a driving setting that prioritizes smoothness and composure over maximum sharpness. In practice, it typically changes how the car responds (throttle mapping, shift behavior, and steering feel) to make it easier to drive at steady speeds.

“Sport Plus” is a drive-mode setting that typically sharpens throttle response, steering feel, and transmission behavior to make the car react more quickly. The speaker says it becomes “more precise” and “less hyperactive,” meaning the mode changes the car’s control calibration to feel calmer while still being more engaging.

“GT” stands for grand touring, a style of car focused on comfortable, composed high-speed driving over long distances. The speaker uses it to describe how close the car’s behavior is to Bentley’s GT character—more refined and controlled than a purely sporty setup.

“Conti GT” is shorthand for the Bentley Continental GT, a grand touring model known for combining comfort with strong performance. Here, the speaker says the discussed car setup “brings more out of” the Continental GT by improving steering/traction behavior and suspension/damper effectiveness.

Air springs use compressed air instead of steel coils to support the vehicle, allowing ride height and spring stiffness to be adjusted. The speaker says the damper setup on the air springs is part of why the car “works much better,” improving control and ride behavior.

A “damper set up” refers to how the shock absorbers are tuned to control body motion—how quickly the suspension compresses and rebounds. The speaker links damper tuning (especially with air springs) to better grip and more predictable road feel.

Dynamics refers to how a car behaves in motion—how it accelerates, brakes, turns, and responds to steering. It’s often used to summarize tuning choices like suspension setup, steering feel, and traction behavior rather than just raw power.

Lag is the delay between pressing the accelerator and getting the expected response from the engine or turbo system. It often comes up with turbocharged setups, where boost builds after a brief wait, affecting how quickly the car feels like it’s accelerating.

The hosts discuss driving the car on the Isle of Man, emphasizing tight, twisty roads and how that kind of route tests precision and control. This is a driving-context segment rather than a technical deep dive.

“Tight and twisty” describes roads with frequent, closely spaced corners and limited straight-line distance. That environment highlights steering response, braking consistency, and traction management more than top speed.

Software tuning is adjusting a car’s control systems—like throttle response, shift logic, traction/drive modes, and other calibration parameters—to change how the car behaves. In this segment, the hosts emphasize that tuning can be informed by multiple track programs, not just one set of performance data.
