Make Every Curve a Highlight Reel with a Detroit Speed C2/C3 Corvette Full Vehicle Kit

The Corvette has long been America’s sports car. While the styling of the C2 and C3 remains timeless, their decades-old suspension technology just doesn’t compare to the ride, handling, and steering precision of today’s performance machines.

Detroit Speed C2/C3 Corvette Full Vehicle Kits will bring your vintage ‘Vette into the modern age. The matched suspension components are engineered to deliver sharper handling, greater driver confidence, and a more refined driving experience.

The kits are built around Detroit Speed’s SPEEDRAY™ front and DECAlink™ rear suspension technologies:

The SPEEDRAY front coilover conversion system completely replaces the OEM components. It features modernized geometry with coilover shocks and tubular control arms plus rack-and-pinion steering. You’ll enjoy quicker response, better control, and more confidence every time the road twists or turns.

Out back, the DECAlink independent rear suspension (IRS) maximizes traction and vehicle control by keeping the rear tires planted through corners, acceleration, and braking.

Combined, these upgrades create a balanced, composed handling package that allows classic Corvettes to hang with modern-day performance cars.

The kits are available in three packages that provide progressively higher levels of performance and adjustability.

Level 1: Street Performance
Perfect for street-focused restomods and weekend cruisers, Detroit Speed’s Level 1 Corvette Full Vehicle Kit delivers a dramatic improvement in handling over stock with good manners for everyday enjoyment.

The kit includes:
• SPEEDRAY front suspension with premium Corvette hub‑pack uprights
• DECAlink rear suspension with factory-type connections to the OEM differential
• Detroit Speed-tuned non-adjustable coilovers
• Upgraded CV axles and stub shafts

Level 2: Street-Friendly, Track-Ready
The Level 2 Corvette Full Vehicle Kit is intended for aggressive street cars, high-horsepower builds, autocross, and occasional track-day use where some degree of road comfort and more adjustability and control are desired.

This kit includes everything in the Level 1 Kit, and adds to it with:
• SPEEDRAY™ front suspension with forged aluminum uprights
• Quick-ratio power steering
• Detroit Speed/JRi-tuned single-adjustable coilovers
• ZR12 IRS differential
• 800 horsepower-rated CV axles

Level 3: Competition-Caliber Performance
If you’re building your C2/C3 into a dedicated Pro-Touring, autocross competitor, or frequent track day car, you’ll want the Level 3 Corvette Full Vehicle Kit. It’s for drivers seeking the ultimate cornering capability and chasing the lowest lap times.  

Building on the Level 2 Kit foundation, the Level 3 Kit ups the ante with:
• SPEEDRAY front suspension with fabricated mounting for additional strength
• JRi double-adjustable coilovers
• ZR12 IRS differential with REM-polished gears
• 1,200 horsepower-rated heavy-duty CV axles

Not ready for a complete suspension overhaul? Detroit Speed’s modular approach lets you build your Corvette in phases, adding performance as time and budget allow while staying on the path to a fully engineered handling package.

Detroit Speed C2/C3 Corvette Full Vehicle Kits fit all 1963-1982 Corvettes equipped with small block, big block, or GM LS engines.
