The reason why i need other brakes is that i have to register my car in sweden as a rebuilt car, than you have to change engine,gearbox,diff and brakes including brakecylinder. After that is done and i got an ok it is much easier to join all kinds of trackday. A little bit difficult to explain though it it concerning the laws in sweden
Anyway it must not be BIGGER brakes but a little bit bigger brakes rear could not be bad now when i got M3 E36 brakes in the front.
Personally i am pleased with my rear brakes, today i drive with original brake disc and just a little bit better brake pads (no racing stuff) for next season the plan whas to try full racepad even at the rear but now it´s a change of plans, some kind of brake modification is on my wishlist.
So now guys, is there any bolt on brakes from BMW,perhaps a little bit bigger
