is what i'm talking about
soft, degradable rubber
powerflex for example, makes EVERY OTHER bushing in a urethane variant... so why not this one?
i know the major upgrade is to go a full M3 rear setup, but for those who aren't quite there, or who just want to run standard rear shocks... why is there no upgrade?
