My most recent upgrade was a full brake overhaul! I picked up a set of f30 grey unpainted (340mm) Brembos from a fellow member over on f30 post, I also purchased a new set of rear E90 335i brakes! I went with these in the rear to both help even out brake bias, and because retrofitting f80 rears or 135 rears was a lot of work and I wanted to do a budget "bigger" Brake kit.
Very happy with the results, The brakes are very powerful and driving it feels great. Pedal still feels like stock after coding +SPBR. same linear feel, obviously more braking force.
Front f30 brembos are bolt on to all e90/92. Rear 335 calipers and rotors are only bolt on for AWD e90 328 and wagon 328 as they have the larger rear parking brake shoes from a 335. RWD 328 need a parking brake mod to work, a few threads cover it.
