6-Piston Front Big Brake Kit

Constructed from aerospace-quality aluminum, the one-piece forged calipers provide unparalleled strength, light weight, and corrosion resistance. The calipers feature aluminum pistons protected by heavy-duty seals capable of withstanding racetrack temperatures. An opposed-piston design ensures consistent brake pad grip and wear, while high-temperature seals, titanium brake pad retainer clips, and stainless-steel wear plates are standard. The kit includes lightweight two-piece rotors, available in drilled or slotted styles, crafted from 6061-T6 aircraft-grade aluminum center sections. This design reduces rotational mass for improved brake response and minimizes rotor warping due to heat expansion. Ksport recommends cross-drilled rotors for daily drivers due to their cooler operation, while slotted rotors are suggested for vehicles seeing more track time. Standard equipment includes D.O.T. compliant stainless-steel braided brake lines for improved pedal response and feel, as well as SC5 Street Pads for optimal street and occasional track use. An upgrade to RCI Race Pads is available for extreme track conditions. This kit is made to order and is non-refundable. It is compatible with BMW E90, E91, E92 3-Series models from 2006-2013. The big brake kits fit 2WD vehicles only and excludes AWD sedan models until 2011.
