1972 Chevrolet Corvette Stingray Coupe - LS3 / TKO600 / RideTech / Baer - Autocross Build
If you're looking for a C3 that's been built to drive-not just sit-this 1972 Corvette Stingray Coupe checks all the right boxes. It's a purpose-built autocross/handling package with modern LS3 power, a Tremec 5-speed, serious suspension geometry, big brakes, and wide Forgeline wheels/tires to put it all to work. Finished in PPG White Pearl over a black interior with Braum Racing Alpha-X buckets, this is a C3 that feels tighter, sharper, and more "modern" than stock in every way.

The Drive
This is the kind of C3 that makes sense the second you turn the wheel. The quick-ratio Borgeson steering, RideTech geometry, and wide Forgeline/BFG setup give it real front-end bite and stability-then the Baer brakes scrub speed with confidence. Add the cammed LS3 and TKO600 5-speed, and you've got a Corvette that's equal parts aggressive, responsive, and flat-out fun-built to run cones, carve back roads, or just deliver that modern performance feel in a timeless Stingray shape.
