CSOhara Steering Rack Stopper - GR86/BRZ
This is a steering rack stopper made from POM - Polyoxymethylene. Prevents wheel rim scratches due to inner interference when installing wider rim wheels. Include 2 pieces with stainless steel boot band (SST not required.)
CSOhara Rear Member Collar - GR86/BRZ
This aims to increase traction by suppressing the movement of the rear member bushing. The collars that match the shape of each bush suppress outgoing movement, and the curved aluminum plate shields the cavity inside the bush and exerts a suppressing effect internally as well.
