Transform your braking with the factory BMW performance braking system for F-series 1 Series, 2 Series, 3 Series and 4 Series. This OEM retrofit package brings serious deceleration, firmer pedal feel and excellent fade resistance, all wrapped up in striking M Performance Orange callipers with the coloured M logo. If you are searching for an uprated brake conversion for your F2x or F3x BMW, this is the official BMW kit that delivers road confidence and track-day composure.

We run this setup on our own cars and regularly install it for customers who want genuine BMW quality with a noticeable jump in stopping performance. Feedback is consistently positive, with owners praising the instant bite, repeatable braking and the way the orange callipers look behind open-spoke wheels.
