Hey everyone, I've been looking around for brake kits for my two W163's both with 17 inch wheels. All I've found is OEM spec brake but I'd like something a little more performance oriented. I've seen the sizes 303mm and 345mm thrown around a bit, will any 5 lug 303 or 345mm rotor and caliper fit, provided it can clear the inside of the rim? Or is there some other dimension I need to verify for a fit? I'm not well versed in brakes and this will be my first DIY brake job, I'm fairly confident but worst case scenario I have mechanic and handy friends and family if I do need help. Any suggestions and active links are appreciated, thank you!
