The Wilwood AERO4 rear big brake kit bolts to the OEM rear axle and reuses the factory parking brake assembly, pairing forged four-piston W4AR calipers in black powder coat with 14.00-inch GT slotted rotors to add stopping capacity behind 18-inch and larger wheels on the BMW E90 325i and 328i. The Spec-37 iron rotors run a 72-curved-vane internal design with a black electro-coat finish, and the kit ships with BP-20 compound pads, parking-brake mounting hats, and a rear stainless flexline kit. Caliper output is matched to the OE master cylinder, ABS function, and factory brake bias.
