Performance Nissan Racing - Upper Control Arms

For those of you who want to adjust your front camber and easly switch it out for daily driving or track use then here you go.

Have your Daily Driving set up. When you get to the track. Jack up your car like you are changing a front tire, take off 2 bolts and remove the shims, replace with the best shim combination for your desired camber setting, tighten bolts, and BAM! Still in alignment spec with an aggressive camber for tackling those corners! when you want to leave the track, put in the shims for street use and drive home with a nice low tirewearing camber angle...
