I only had a chance to compare my M Sport brakes to a fresh 3 Series loaner's basic ones. I was surprised with the difference! I used to think it was only about high speed (minding tyres grip over brake strength as well
) and intensive usage overheating too. But even when braking quite unintensively (I hate to brake
) from low city speeds I felt somewhat unsure whether the basic brakes car would stop ("Do I need the handbrake?"
). No doubt the car was all right technically. M Sport brakes just feel so much more confident. Now I believe they are a "must have" if available. (And the whole M Sport package too!
)
