At SEMA 2025, the lights are unforgiving — especially if you bring a black car. But that didn’t deter Bryce Green and the team at Big Kid Customs. Instead, they used the spotlight to showcase one of their most refined builds to date: a sleek, black C2 Corvette sitting over a Full Speedtech Performance EXTREME C2 IRS chassis and suspension system.
“Everyone tells us we have balls bringing a black car under light to SEMA,” Bryce joked. “But it paid off. The paint looks insanely wet, and this car just hits from every angle.”

A Builder That Does It All — And Owns Every Detail
Big Kid Customs isn’t just an assembly shop — they do fabrication, paint & body, mechanical assembly, and full interior in-house with a team of roughly 20 highly skilled builders.
“We have full control over everything,” Bryce explains. “Interior, paint, fab — we’re not outsourcing the craftsmanship, which makes a massive difference for fit, finish, timing, and quality.”
With 16–17 cars in active build rotation and a 3–4 year waiting list, the market agrees. Twin-turbo Lincolns, ’57 Buicks, multiple Camaros, more Corvettes—including two split windows—cycle through the Northern Utah facility, and they’re still hiring more talent to keep up with demand.
Powertrain & Interior: Modernized Without Losing Soul
Under the flawless black hood sits a C7 LT1 powerplant paired with a 4L60 transmission, breathing through an all-new cooling system and dressed with custom coil pack covers. Vintage Air keeps the cabin cooled, while Dakota Digital and RetroSound electronics bring modern function into classic packaging.

Apex Leather upholstery
Custom carbon fiber dash, paint-matched to the exterior
Fully integrated interior built in-house
A black car with chrome and carbon accents is not subtle — and that’s the point.



Wheels, Chrome, & Stance: The Fitment That Matters
Underneath the meticulously polished body sits a set of Schott Wheels, a 20-inch style that pairs cleanly with the brightwork handled by Ogden Chrome.



Bryce summed it up perfectly:
“Wheels are like a woman’s shoes — they make or break the outfit.”
On this car, they certainly make it

Where Speedtech Comes In: The Foundation
When Bryce talks about the build, he starts from the bottom — literally:
“First off, probably the most important thing is your chassis. We’ve got the full Speedtech chassis underneath this. Full suspension, brakes, everything from Speedtech. This thing handles like it’s on rails.”
The owner drives the car. Not just once a year. Not only onto a trailer.
Actually drives it.
That’s exactly the mission of the Speedtech EXTREME line.

Tech Spotlight: Speedtech’s EXTREME C2 IRS Chassis
The C2 Corvette is iconic, but anyone who has driven one on modern roads knows the limitations of the original factory platform. The EXTREME C2 IRS chassis solves that by replacing 60-year-old geometry with modern motorsport-grade engineering.

✔ Independent Rear Suspension for Real Grip
A modern IRS system dramatically increases traction and stability—especially on imperfect roads or high-speed highway sweepers.
✔ Large Tire Fitment Without Cutting Up Soul
Designed for 315+ rear tires and aggressive front fitment, enabling real grip and real braking performance while keeping the exterior body untouched.
✔ Rack-and-Pinion Steering
Correct steering feel and reaction without the slop and slow ratios of factory C2 steering.
✔ Modern Coilover Shock Options
Compatible with QA1 MOD Series, JRi, or customer-selected coilover systems for tuning from “award-winning show car” to “road-trip to autocross.”
✔ Engine Swap Freedom
Small block, big block, LS, LT — the packaging is designed to fit modern drivetrains cleanly without firewall nightmare scenarios.
✔ Built for Drivers, Not Just Displays
The C2 chassis is engineered so the car can actually be used:
highway cruises
canyon drives
autocross days
national events
long-distance road trips
This is why shops like Big Kid Customs spec them — it elevates the Corvette from nostalgic artifact to a modern performance car
