So i'm looking at upgrading my bushings/mounts to go with my coilover install
i like powerflex
but they have PFR5-416-12 and PFR5-416 (10mm, standard?)
my coilovers are BC Racing, and i have NO IDEA if they're 10mm or 12mm, nowhere can i find this information, and i don't have a 10mm nut handy (or a 12mm one) to check it out
ED: i'm 99% sure it's 12mm, but it fits in the OEM mount? which is 10mm? how does this work?
