M-Sport (blue) brakes

helmet91 · 03-13-2021, 02:05 PM

Long story short, I bought my G20 330i M-Sport off the lot and it isn't equipped with the M-Sport brakes. I'd like to do the upgrade and have found a really nice set taken off a G21 M340.

- Are the rotors the same size?
- I'm wondering because my winter wheels are 18x8 ET28 BBS XRs and I don't know if they'll fit. Tire Rack shows them fitting the 330i with M-Sport brakes

- It looks like the calipers, rotors and pads are included. What else do I need for the upgrade?

Thanks!

im not 100% sure about any of this, but id imagine you'll need the m-sport dust shields as well, and will possibly need to code for the upgraded brakes, and im sure the m-sport rotors are bigger, a quick call to the dealer asking for part numbers should tell you, and you should have no problem fitting them with 18"s.
