This Kit replaces your stock rear upper control arm bushings with less compliant polyurethane bushings, and an a-symmetric center section.  This will allow you to adjust to +/- 1 degree of camber.  This will allow you to run a much more aggressive camber setting, and is ideal for track or Auto-Cross applications.    

This kit will work on all  DC5 RSX and RSX-S (02+).
