Damage to the torque boxes are a common problem. Stiffer, aftermarket control arms are a necessity on these cars... but the added strength in the arms is just that much harder on the torque boxes (particularly the uppers).

There are several aftermarket products to fix and prevent it. My favorite is the Wild Rides Battle Boxes. Last set I purchased were around $100 for uppers and lowers. I also purchased the same Wild Rides lower kit for another car, but i substituted a BMR brace kit for the uppers. More spendy, but it uses tubular bracing that connects to the frame for added strength. It's going in a 500+ hp 82gt I'm building.
