A 590hp LS3, 335mm-wide rear meats and a retro livery that screams “’Murica!” on Kyle Tucker’s 1972 Corvette and tell us plenty about the car’s go-fast intentions. To celebrate Independence Day, we’re featuring this C3 that started as founder of Detroit Speed’s test mule that elevates the Detroit Speed C3 Corvette handling to race car levels thanks to a ground-up suspension overhaul. Undeniably, everything under the skin is optimized for one thing: domination on the autocross.

DSE Develeopment

In true competition form, Kyle’s Corvette skips the typical worm clamps, NPT fittings, and thread sealant mess. Instead, the car uses AN fittings throughout. The fuel rails, radiator hoses, brake lines, oil lines, even the coolant overflow tank use An fittings. Which make servicing easier and leak free under pressure.

And those fittings aren’t just for show. They’re linked to real race gear, including a dry sump oiling system and tandem master cylinders. Kyle’s no stranger to autocross abuse. He knows a wet sump engine or basic proportioning valve just won’t cut it under heavy braking or long sweeping corners.

At a glance, the car’s Greenwood-inspired livery pays tribute to the Le Mans C3s of the 1970s. Don’t mistake the Detroit Speed C3 for a tribute build, it’s a pure performance machine. Detroit Speed engineered an entirely new front and rear suspension setup. It replaces the factory leaf springs with coilovers, adds high clearance drop spindles, and upgrades the front geometry with revised control arms. The real masterpiece is the rear suspension. DSE ditched the factory layout and designed a multilink IRS that uses CV joints instead of U-joints. A cast-aluminum cradle supports forged uprights, eliminating lateral load on the driveshafts and making the suspension race ready.

The Grunt And Grip

The steering got an upgrade too. A custom DSE power rack and pinion system keeps things tight and responsive without compromising drivability. And with 315mm BFGoodrich Rival S tires up front, the car’s grip demands every ounce of precision.

For power, DSE turned to Mast Motorsports, sourcing a 416ci LS3 stroker good for 590 horsepower. It’s paired with a NASCAR spec Hightower four speed manual. Brembo six piston calipers bring it all to a stop. To make room for the massive rolling stock and upgraded chassis, Detroit Speed modified the body with custom fiberglass fender flares inspired by L88 designs. Even the front and rear steel bumpers were replaced with fiberglass units, finished off with an LT-1 hood.

Despite wrapping the car just hours before competition, it debuted at the 2016 Goodguys Raleigh event and won its class immediately. Unsurprisingly, Tucker and the DSE crew aren’t finished. The car continues to evolve, logging valuable testing miles as Detroit Speed launches C2/C3 suspension parts and upgrades.
