While the factory gave us a strut tower brace for the GTO, unfortunately it is little more than a cosmetic piece. The factory brace is made from thin wall 1" x .083" seamed tubing and does little to reinforce the strut towers. The BMR strut tower brace is made from 1-5/8" x .095" seamless tubing and uses heavy duty 3/16" mounting plates. NOTE: Some manual '05-'06 cars may require bending the clutch reservoir bracket for proper clearance.Learn More
