Those look like control arms I can afford! A little concept insight beyond the pictures would be appreciated. I'm assuming this is how the trans-am boys eliminated flex back in the day?
Scott it's a way to eliminate flex but also keep the factory arms from cracking under load. The stamped arms tend to crack right behind the ball joint so plating the underside keeps the loads more evenly distributed. I've done a few different sets like this. Cheap way to add strength to the LCA's
