The C2 and C3 Corvette's are known to have flexing issue at the steering box when running a wider tire on the front. This was an issue that has needed to be addressed for years. During the 48 Hour Corvette build, we built a prototype steering box brace as a bolt-on reinforcement. This bracket is designed to work with the Borgeson power steering box and will simply bolt on to your existing system in just minutes. The 48 Hour Corvette runs a 315-30-18 tire all the way around while seeing more abuse on the autocross and road course than any car should have to endure. The frame and box flex is now a thing of the past, thanks to this bracket we are now offering to the public. Purchase yours today! .
