LS3 / TKO600 / RideTech / Baer — Autocross Build

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.

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.
