Supercomp Rear Big Brake Kit

The Ksport Supercomp Rear Big Brake Kit is engineered to provide superior stopping power for the BMW F31 3-Series Wagon. This kit is made to order and includes 380mm x 32mm rotors paired with a 6-piston caliper configuration. The SuperComp caliper, forged from aircraft-quality billet aluminum, features a differential bore design with larger pistons than the ProComp series, weighing just over 7lbs. It includes aluminum pistons, high-temperature seals, titanium brake pad retainer clips, and stainless-steel brake pad wear plates, with an opposed piston design enhancing pad wear and caliper rigidity. The kit incorporates 2-piece floating disc assemblies designed to reduce weight and thermal stress, preventing disc warping. Rotors feature a unique slot design to minimize noise and expel debris, with cross-drilled options recommended for daily driving to run cooler. Standard configuration includes Ksport SC5 Street Pads, designed for optimal performance in street and occasional track conditions with optimal operating temperatures between 194°F – 1022°F, and significantly reduce brake dust and noise. An optional upgrade to Ksport RC5 Race Pads is available for extreme track use, featuring carbon metallic compound with optimal operating temperatures between 482°F – 1472°F and are not recommended for street use. The kit also includes D.O.T. compliant stainless-steel braided brake lines to improve pedal feel and response. It is compatible with the BMW 3 Series F30/F31/F34 models from 2012-2019, including the 328d (N47 2.0L), 328d xDrive (N47 2.0L), 328i (N20/N26 2.0L), and 328i xDrive (N20/N26 2.0L). Options for caliper color, street or race pads, and center bell upgrades are available at additional costs. Please note that Ksport Big Brake Kits are made-to-order and are non-refundable.
