Hey guys i have a question. So first, will a f30 BBK fit on a f32. Second, if i have the stock rotors that came with the 17inch wheels for my f32, will either the m sport brake kit or the m performance brake kit fit on it? I upgraded my wheels to the 19s with the same rotors on. I am aware that you need the front and rear rotors to install the m performance brake kit but what about for the m sport blue ones?

So basically, if i were to upgrade to the m sport blue brakes, what do i have to change?

Thanks guys

Calipers, pads, back protection plate to suit larger rotors and 370mm rotors

1. The Blue Caliper M Sport Brakes are also available with 340mm rotors in front. So make sure you get the set you want!
2. 370mm rotor will need 18" wheels at least! However, not all 18" wheels will fit.

For the m sport brakes what is the smallest size tht rotor that i can use for the front and rear

[ahero4eternity]

So you want big calipers and small rotors? lol

The front caliper are different for the 370mm and the 340mm brake disc. (naturally, how else should it fit?)

The rear brake disc for the M Sport Brake is always 345mm.
However there are different parts to fit the different hand-brake/emergency-brake setup.
