Questions on brake upgrade - BMW 3-Series (E90 E92) Forum

nitty90 · 09-17-2009, 09:04 AM

Hello guys..newbie here from Singapore. Currently i am running my E90 325i on the BMW performance brakes for the front and rear with fronts rotors @ 338mm and rear @ 334mm(i think) and i would like to upgrade to the M3 ones with 358mm front and 350mm rear with the front 6 pots brembo calipers and 2pots rear. any gurus can advise if the rotors are a direct fit with no modification or need to custom made additional brake carriers to fit those m3 rotors.

Thanks alot!!!!

I have no idea but let me just say those brakes look awesome. You wanna send your old ones my way?

Can't comment on the front disc, but the rear for sure won't fit.

You might as well get the actual brembo BBK kit instead of the M3 version, they will fit for sure.

Unless you are Mario Andretti and a serious track hound I seriously doubt you need even the BMW BBK, let alone anything else. Except for "bling" that is.

Will not fit. And a +1 on the advice that you should save your pennies and spend them on something else. Those brakes are as good as anything for street use, and if you are going track then there are better systems than the M3 (e.g., stoptech trophy).

If you are looking for better performance from those brakes, upgrade the pads and add stainless steel lines might be all you need.
