Will Brembos from a 2 series fit my 430i?

Bradze81 · 03-17-2023, 11:44 AM

I have a ‘19 430i that I would like to start using for lapping days but my wife is set on keeping the extended warranty in tact. Think I could get away with buying the brakes from an M and slapping them on. I’m happy with most of the stock stuff even though it is base level everything. I keep seeing Brembo brakes from 2 or 3 series and it says it fits 4 series F30 and F34 but it is eBay and the sellers are clueless. I’ll rebuild the calipers

Yes however the M235i/M240i blue brakes are 340mm not 370mm. You can tell which version they are because the rotor size is stamped on the back of the caliper

6cyl F3x (silver calipers, brembro front only)= 340mm /330mm
F20/F30 4cyl msport brake blue calipers= 340mm/345mm
F3x 6cyl msport brake blue calipers = 370mm (/345mm
Mperf brakes = 370mm/345 mm
f8x brakes = 380mm/370mm
