1-Piece Caliper Kit with Aluminum Pistons

The Ksport Procomp Rear Big Brake Kit is engineered to provide the ultimate stopping power for your BMW E36 3-Series. Constructed from a solid billet of aerospace-quality aluminum, the lightweight, forged one-piece calipers are built for unparalleled strength and corrosion resistance. The opposed-piston design ensures consistent brake pad grip and wear, while high-temperature seals, titanium brake pad retainer clips, and stainless-steel brake pad wear plates are standard. The center sections are crafted from 6061-T6 aircraft-grade aluminum, acting as effective heat sinks to dissipate heat away from the rotor. Rotors are available in either Cross Drilled (recommended for daily drivers as they run cooler) or Slotted (recommended for track use) styles. This kit includes D.O.T. compliant stainless-steel braided brake lines, which reduce line expansion under pressure for quicker pedal response and a firmer pedal feel compared to stock rubber lines. Standard SC5 Street Pads are included, offering optimal braking performance for street and occasional track use with reduced dust and noise. An upgrade to RCI Race Pads is available for extreme track conditions. Note that this product is made to order and is non-refundable. The kit is confirmed to fit 2WD BMW 3 Series models from 1992-1998, including the 320i, 323i, 325i, and 328i.
