Through an extensive testing program, Detroit Speed, Inc. has discovered there are substantial improvements that could be made over the original rear chassis braces. By triangulating the rear crossmember, frame rail and upper control arm mount, we were able to reduce deflection within the rear section of the chassis.
While designed as a replacement for A-Body cars originally fitted with rear braces, these can be installed on cars originally built without the braces with minimal effort, for substantial structural improvement.
