I have both Front/Rear SPC Camber Kit...I was inspecting the rear ones and it seems that the rubber boot is ripping/disintegrating. I was wondering if you can just buy the rubber boot and fix it and not have to buy the entire control arm or ball joint?

 

there's a warranty on them ( i think lifetime) that should cover a replacement or a fix it on the rubber boot. I doubt you can just buy the rubber boot separately..
