About this episode

Travis Smith’s path from Lamborghini Super Trefeo to endurance at Daytona sets the stage for a conversation that links trackside engineering to trailside chaos. The crew chief breaks down how suspension tuning, driver feedback, and quick pit-lane diagnosis help teams deliver cars to the green flag. We also get real numbers for IMSA budgets, then pivot to safari-style air-cooled 911s heading for Moab—built to be driven hard, with sticker tires, rally-inspired hardware, and even motorsport ABS ideas.

Lambo team

"Kevin's jealous. I find out this guy is plugged in with the Lambo team. He's, he's doing like the 24 hours of Daytona."

“Lambo” is short for Lamborghini. If someone is “with the Lambo team,” it usually means they’re working with Lamborghini’s racing program.

Topic

24 hours of Daytona

"Kevin's jealous. I find out this guy is plugged in with the Lambo team. He's, he's doing like the 24 hours of Daytona. He's doing all these crazy races."

The “24 Hours of Daytona” is a race where cars run for an entire day. It’s less about one fast lap and more about staying reliable and managing stops and driving for hours.

Concept

off-roading Porsches

"We're talking about off-roading Porsches. Yeah. Quite the extremes, man. We're on, we're on Daytona, right?"

Off-roading a Porsche means taking it onto dirt trails and rough terrain. It’s harder than normal driving, so you typically need the right tires and setup to handle traction and bumps.

Concept

Lamborghini Super Trefeo

"Yeah. So we have a team that races in Lamborghini Super Trefeo. It's a, it's a series that runs in Imsa. All the cars are, it's basically like spec racing."

“Lamborghini Super Trefeo” is a racing series where most teams run very similar Lamborghini cars. Because the cars are so alike, it’s more about driving and team work than buying a “faster” car.

Concept

spec racing

"It's a, it's a series that runs in Imsa. All the cars are, it's basically like spec racing. All the cars are the same."

Spec racing means everyone races with cars that are very similar. That makes the race depend more on driving and team setup than on having a totally different (and faster) car.

Company

IMSA

"Yeah. So we have a team that races in Lamborghini Super Trefeo. It's a, it's a series that runs in Imsa."

IMSA is the organization that runs a lot of sports car racing in North America. If a series is “in IMSA,” it usually means it races on IMSA event weekends.

Term

suspension setup

"parameters we're allowed to adjust and whatnot, mainly around like the suspension setup and [145.3s] arrow setup."

Suspension setup means how the car’s suspension is adjusted for the track. Small changes can make the car feel more stable in turns and easier to drive fast.

Concept

crew chief

"You're, you're running and [150.8s] campaigning your own Lambo in this club or in this class? Nope. This one, I'm crew chief for a team [156.8s] and the race, the two of the racers themselves own, own the cars."

A crew chief is basically the team’s lead for race-day. They coordinate the crew, work with engineers, and make sure the car is set up and ready to go.

Term

tuning

"And then we work through with our engineers on tuning. We have coaches that work with the drivers [190.3s] on, you know, on what they're doing and just making sure, you know, my main job is to make sure"

Tuning is tweaking the car’s settings so it drives better and faster. Engineers use data and driver feedback to dial it in for the track.

Term

green flag

"do their jobs, [200.7s] as efficiently as possible and, you know, deliver the cars to the green flag. [208.3s] Yeah, man."

The green flag means the race has started and drivers can go. Teams time their prep so the car is ready right when it happens.

Topic

cost of racing / season budget

"You got a lot on the line with, you know, these events are super expensive and someone's paying for it. And so you'd never want to let anyone down. So yeah. How much does it cost when you say super expensive?"

They talk about what racing costs, including the car price and the extra money needed to keep the car running. They also mention that testing and preparation can drive the budget up.

Concept

GTD cars

"No, we do five races a year with the IMSA series, like the GTD cars are, they have tons of races. So we don't go to all of them."

GTD is one of the categories in IMSA racing. It’s for cars that are based on production models, but set up for racing. The speaker is saying their team doesn’t race every single event in that category.

Concept

World Final in Italy

"We'll do five races here in the US and then we'll do the World Final in Italy. That's in October."

A World Final is the big end-of-season event where teams travel to race internationally. Here, they’re saying they do some races in the U.S. and then also go to the final event in Italy. That adds travel and expense on top of the normal season.

Concept

seat time

"But what is that seat time and knowing all these positions that does it help you manage this team?"

Seat time means how long a driver actually drives the car. More seat time usually helps someone understand how the car feels and how to improve it.

Concept

set the cars up

"But what is that seat time and knowing all these positions that does it help you manage this team? And what is your role in the mechanism as far as, you know, set the cars up, but how entailed is that?"

“Set the cars up” means adjusting the race car so it handles the way you want for a specific track. It can involve setup changes beyond just driving.

Car

Porsche GT4

"So I, with Pinnacle Motorsports with my company, we mainly race Porsche GT4s."

The Porsche GT4 is a Porsche made for track driving. Here, the speaker is saying their racing team mainly races Porsche GT4 cars.

Company

Pinnacle Motorsports

"So I, with Pinnacle Motorsports with my company, we mainly race Porsche GT4s."

Pinnacle Motorsports is the racing team/company the speaker works with. They use it to run their Porsche GT4 racing and track testing.

Concept

endurance

"And those cars I'll race, we'll race those in endurance, more like a club level racing, World Racing League, WRL, AER, things like that."

Endurance racing is long-duration racing where you have to keep the car working and the drivers consistent. It’s not just about one quick burst of speed.

Part

damper change

"The car is doing this, I feel like it's, you know, should be a damper change or bar change or some other tweak to hopefully it helps you kind of figure out what, what he's feeling out there on the track so you can set it up better for him the next lap."

Dampers are shock absorbers that control how the suspension moves. If you change them, the car can feel more stable or more comfortable over bumps and in corners, which helps the driver understand what’s happening.

Part

bar change

"The car is doing this, I feel like it's, you know, should be a damper change or bar change or some other tweak to hopefully it helps you kind of figure out what, what he's feeling out there on the track so you can set it up better for him the next lap."

A sway bar helps keep the car from leaning too much when you turn. Changing it can make the car feel like it turns more easily or feels more planted, depending on how it’s set up.

Concept

set it up better for him the next lap

"The car is doing this, I feel like it's, you know, should be a damper change or bar change or some other tweak to hopefully it helps you kind of figure out what, what he's feeling out there on the track so you can set it up better for him the next lap."

“Setup” means tuning the car so it handles the way the driver needs. They listen to what the driver feels, make changes, and then try again on the next lap to go faster and be more consistent.

Concept

make repairs on the fly

"when something goes wrong, something, a part breaks or something like that and they're coming in and you have to make repairs on the fly. The most information you can have, you know, they might be limping around the track for two minutes to get into you"

That means fixing the car quickly during the event when something breaks. The goal is to get the car back running safely so the driver can keep going.

Concept

limping around the track

"The most information you can have, you know, they might be limping around the track for two minutes to get into you and that two minutes is pretty valuable."

“Limping” means the car can’t drive normally, so the driver has to go slower or with limited ability. What the driver reports while it’s limping helps the team figure out what broke.

Part

roll cages

"So the cars come factory built, so you could literally take them off the truck and go race them. I mean, they got the roll cages and the harnesses and all that stuff in them."

A roll cage is a strong metal frame inside the car that helps protect you if the car flips or crashes hard. Race cars use them to make the cabin safer.

Part

harnesses

"So the cars come factory built, so you could literally take them off the truck and go race them. I mean, they got the roll cages and the harnesses and all that stuff in them."

Harnesses are racing seat belts with multiple straps. They hold the driver more firmly during aggressive driving and crashes.

Part

coil springs

"But what we are allowed to change, we tweak quite a bit, like there's several sets of coil springs that we can put on the suspension. So we're doing, you know, that's probably the biggest component that we're going to change is the spring rates."

Coil springs are the suspension parts that absorb bumps and help control how the car leans. Swapping spring rates changes how the car feels and grips in turns and over rough track sections.

Term

adjustable rake

"You know, we have adjustable sway bars, we have adjustable rake, wings, we have high downforce components in the front end or low downforce components in the front end."

Rake is how much higher or lower the car sits at the front compared to the rear. Changing it can change how the car sticks to the road and how it behaves in turns.

Part

adjustable sway bars

"You know, we have adjustable sway bars, we have adjustable rake, wings, we have high downforce components in the front end or low downforce components in the front end."

Adjustable sway bars help control how much the car leans in corners. By changing them, the team can make the car turn more predictably and balance grip front to rear.

Term

downforce

"we have adjustable rake, wings, we have high downforce components in the front end or low downforce components in the front end."

Downforce is the “suction” effect from aero parts that makes the tires grip harder. It helps the car corner faster, but it can come with tradeoffs like more drag.

Part

wings

"we have adjustable rake, wings, we have high downforce components in the front end or low downforce components in the front end."

Wings are aerodynamic parts that push the car down onto the track. More downforce usually means better grip, but it can affect top speed.

Term

camber

"And so in camber, so all that stuff, all the alignment settings."

Camber is how tilted the tire is when you look at it from the front or back. Changing it helps the tire stay in the best grip position during cornering.

Term

alignment settings

"And so in camber, so all that stuff, all the alignment settings. So, so really we're chasing what most people would consider an alignment and then the arrow and the, you know, controlling where the weight is in the car"

Alignment settings are adjustments to the tire angles so the car tracks correctly. Race teams change them to make the car turn the way they want and keep the tires working well.

Term

damping

"Can you change damping? Yeah. Are you allowed to tune damping as well? Yeah. Okay, so pretty much all your tunables are right there, right?"

Damping is the shock absorber’s “resistance” to moving. Changing it helps the tires stay planted instead of bouncing around on rough track surfaces.

Term

spec tire

"I mean, the tires are a spec tire, what we have to run, you know, we have a minimum ride height that we have to stay above"

A spec tire is the same tire everyone has to run. That way, teams can focus on tuning the car instead of chasing different tire brands or models.

Term

minimum ride height

"I mean, the tires are a spec tire, what we have to run, you know, we have a minimum ride height that we have to stay above, which we may stay up above it, you know, a little more in some places"

Ride height is how high the car sits off the ground. If there’s a minimum ride height rule, teams can’t lower the car too much, so they have to tune within those limits.

Term

tire compounds

"...the tire surface, you know, the tire compounds that are on the track surface are different. You have other cars out there running with us that are running Michelin's or, you know, we're running handcooks..."

Tires are made with different rubber formulas. Those formulas change how much grip you get and how the tire acts as it gets hot.

Term

tire surface

"...now the weather's different, the tire surface, you know, the tire compounds that are on the track surface are different..."

The “tire surface” is the part of the track where tires have laid down rubber. More rubber usually means more grip and different handling.

Term

chords

"...our tires will be down to chords in an hour, hour and 15 minutes. And so all that rubber is somewhere..."

As a tire wears out, the rubber gets thin. “Chords” means the tire’s internal reinforcement is getting exposed, and the tire stops working well.

Term

rubber build-up

"...our tires will be down to chords in an hour, hour and 15 minutes. And so all that rubber is somewhere, you know, some of it's built up and thrown around, but it builds up on the surface."

As cars drive, they leave rubber on the track. That rubber can spread around and end up on other cars’ tires, changing how they grip.

Term

compound react

"...it's transferring onto the pavement. And, you know, your compound that you're running in your car will react differently to the compounds that are down."

Tires don’t just wear—they also change behavior with heat and with what’s on the track. If other tires left different rubber behind, your tires may grip differently.

Term

marbles

"...make sure you're staying online because it's not just marbles you're picking up where marbles would be considered like chunks of tire that come off of other cars."

“Marbles” are little bits of rubber from other tires that get loose on the track. They can make the surface slippery and less grippy.

Term

thin layer of rubber

"...you're not just picking up chunks of rubber, but actually like thin layer of rubber off the track surface onto your tires."

Sometimes it’s not big pieces of rubber—it’s a thin film. That film can change how your tires grip, so staying on the clean line matters.

Term

sticker tires

"So we're always rolling out on what we call sticker tires, meaning they still have the stickers from the manufacturer on them. Do you ever run a match set of tires?"

“Sticker tires” just means brand-new tires that still have the new-tire labels on them. Racers use them early because they usually have the best grip when they’re fresh.

Term

match set of tires

"So we're always rolling out on what we call sticker tires, meaning they still have the stickers from the manufacturer on them. Do you ever run a match set of tires? [1036.8s] No, we don't, we don't get into that."

A “match set” means all the tires are chosen to be as similar as possible. The idea is that the car feels more consistent because the tires behave more the same way.

Concept

air cooled 911s

"It's kind of become a thing where you're building these safari Porsches. You're taking these air cooled 911s, lifting them up, putting long travel"

“Air-cooled” means the engine is cooled mostly by air flowing over it, not by coolant in a radiator. Porsche 911s are known for having air-cooled versions, and that’s what the speaker is talking about.

Part

suspension skid plates

"suspension skid plates underneath, built motors, gearboxes, upgraded brakes. And a lot of them,"

Skid plates are armor underneath the car. They help protect the suspension and other parts when you hit rocks or drive over rough ground.

Part

built motors

"suspension skid plates underneath, built motors, gearboxes, upgraded brakes. And a lot of them,"

A “built motor” means the engine has been upgraded and reinforced. It’s done so the car can handle tougher driving without breaking as easily.

Part

upgraded brakes

"suspension skid plates underneath, built motors, gearboxes, upgraded brakes. And a lot of them,"

“Upgraded brakes” means better brake parts than stock. That helps the car stop more reliably when you’re driving hard and repeatedly on rough terrain.

Concept

ground clearance

"at the end of the day, they still have, you know, about 14 inches of ground clearance. So, and, and we have bumpers on them with good approach angles..."

Ground clearance is how much space there is between the bottom of the car and the ground. More clearance helps the car avoid hitting rocks and bumps on trails.

Concept

approach angles

"we have bumpers on them with good approach angles, but at the, you know, in their four, all wheel drive."

Approach angle is how steep a hill or obstacle you can hit with the front of the car before it scrapes. Better approach angles mean fewer hang-ups on rocks and ledges.

Concept

all wheel drive

"we have bumpers on them with good approach angles, but at the, you know, in their four, all wheel drive."

All-wheel drive means power goes to all four wheels. That helps the car grip better on slippery dirt, rocks, and uneven trails.

Car

Porsche 911

"Dude, it doesn't matter. It's a Porsche 911. Seeing that at Moab would blow people's mind. What were their reactions? Everyone's stopping to take pictures of us..."

A Porsche 911 is a famous sports car. Here, they’re talking about classic (air-cooled) 911s that have been modified so they can actually drive hard on trails at Moab, not just sit in a garage.

Concept

water crossings

"We're ripping around doing water crossings. Even when we're just cruising down the dirt roads..."

Water crossings are when you drive through water on a trail. It can be risky because it changes traction and can get water where it shouldn’t, so the car needs to be prepared.

Concept

rally

"ripping around like we're on a rally at, which is what we are doing."

A rally is a type of race where cars drive hard over changing road and dirt conditions. They’re saying their trail driving feels like that—fast, aggressive, and constantly changing traction.

Concept

Dakar 911s

"And this is kind of like the Dakar 911s of the day. Are you kind of mimicking a lot of the same setups as those were?"

“Dakar 911s” is a comparison to Porsche 911s that are built for very extreme rally-raid racing. They’re saying their Moab setups are inspired by that kind of tough, off-road preparation.

Part

custom fabricated control arms

"Yeah, we are. I like, we have custom fabricated control arms on them, king coil over shocks..."

Control arms are parts that connect the suspension to the wheels and help control how the wheels move. Custom ones are often stronger and shaped to work better for off-road driving.

Part

king coil over shocks

"king coil over shocks, you know, like I said, they break upgrades. So they're serious."

Coilover shocks are suspension parts that combine the spring and shock together. Using King coilovers usually means the car’s suspension is tuned for rough terrain so it can absorb bumps better.

Part

electronically controlled suspension

"we have actually electronically controlled suspension on them to help with the sway control."

Electronically controlled suspension uses electronics to adjust how the suspension behaves. The goal here is better stability—less body sway—when driving hard on rough terrain.

Concept

sway control

"we have actually electronically controlled suspension on them to help with the sway control."

Sway control means reducing how much the car leans side-to-side. It helps the car stay more stable when turning fast or hitting uneven ground.

Company

Road Scholars One

"Yeah, the shop that I subcontract to that's actually building them is called Road Scholars. You can see them on Instagram at Road Scholars One, the number one."

Road Scholars One is a restoration shop the host works with. They specialize in very high-end Porsche restorations.

Term

Motorsport ABS

"I was like, well, we should have Motorsport ABS on these cars, like from Bosch Motorsport stuff, not the factory streetcar stuff."

Motorsport ABS is a braking system that helps prevent the wheels from locking up. It’s designed to work better when traction is inconsistent—like on rough or mixed surfaces.

Brand

Bosch Motorsport

"I was like, well, we should have Motorsport ABS on these cars, like from Bosch Motorsport stuff, not the factory streetcar stuff."

Bosch Motorsport is Bosch’s performance-focused parts line. Here it’s mentioned because the host thinks a motorsport ABS setup would be better than the usual factory street version.

Concept

restomod

"we don't want to start with something super nice cause we're going to, you know, cut it up and, and start modifying it. But we do also, you know, road scholars doesn't do anything part way."

A restomod is an older car that gets updated so it drives better today. It usually keeps the classic style, but improves the parts underneath.

Car

Ford Excursion

"..., we want to go have these safaris and have these excursions. And that's kind of part of the deal, not, not of..."

The Ford Excursion is a very large SUV designed for carrying people and towing. The podcast mentions it as part of the setup for trips and adventure driving. Because it’s big and built for work, it can be useful for hauling gear and getting around on longer outings.

Concept

vintage racing

"Porsche going off road, uh, vintage racing, vintage cars that you can get that have all kinds of heritage to them,"

Vintage racing is racing older cars in organized events. It’s about driving classics hard, not just keeping them in a collection.

Concept

road dirt

"That's a badge of honor. Sweet. Yeah. Yeah. On something like that, like road dirt for sure."

They’re talking about the dirt and mess you get when you actually drive the car on rough roads or trails. It’s treated like proof the car is being used for real adventures, not just parked.

Concept

rock chips and scratches

"And probably even just the, the, you know, rock chips and scratches, like it's like, nah, man, that was from Moab."

Rock chips and scratches are the little dents and marks you get when debris hits the car. Here, they’re saying it’s normal when you drive hard off-road.

Concept

Moab

"nah, man, that was from Moab. Bro, you know, some of these cars just got painted... we put a thousand miles on it this week, ripping around Moab."

Moab is a well-known place for off-roading in Utah. It’s the kind of terrain that naturally makes cars get dirty and pick up scratches.

Topic

SEMA show

"And, you know, we're going to clean it up and most likely you'll see it at the SEMA show."

The SEMA show is an annual automotive trade show focused on aftermarket parts, custom builds, and specialty vehicles. Mentioning it signals that the cars being discussed are likely modified or showcased for enthusiasts and industry buyers.

Concept

drag racing

"was racing muscle cars, drag racing, you know, as a kid on the street and all that stuff, going to the drag strip and, and whatnot."

Drag racing is when cars race in a straight line over a short distance to see which one is quickest. It usually starts from a stop, like at the drag strip.

Car

Chevrolet Chevelle

"picked up a hot rod magazine, saw an article about a 66 Chevelle. I don't have that cataloging or that magazine anymore, but I'd like to find a copy of it."

The Chevrolet Chevelle is a well-known American muscle car. The 1966 version is a classic that many enthusiasts still talk about and modify, and that’s the car that inspired the host to get interested in cars.

Concept

hot rod magazine

"picked up a hot rod magazine, saw an article about a 66 Chevelle."

A hot rod magazine is a car magazine that talks about modifying and enjoying cars. The host is saying he read an article in one and it sparked his interest in cars.

Car

Camaro

"I started out with muscle cars, Camaros, when I was a kid, and, you know, putting big V8s and stuff."

A Camaro is a famous American muscle car from Chevrolet. The host is saying he started liking cars with Camaros before he got into other brands.
