Dualcomp Rear Big Brake Kit w/ 4 Piston Calipers

The Ksport Dualcomp Rear Big Brake Kit is an ultimate all-in-one dual-caliper solution engineered for drifting and rally racing applications, specifically designed for the BMW F31 3-Series M-Package Wagon. This innovative system utilizes a single 4-pot caliper, with two pots dedicated to the foot brake and the other two for the handbrake, each running on its own independent system. The kit comes standard with everything needed for installation, including calipers, floating brake discs, brake pads (SC5 Street Pads included, with an option to upgrade to RCI Race Pads), and all required hardware. This Big Brake Kit is also Formula Drift legal. The calipers are constructed from lightweight, forged one-piece aerospace-quality aluminum, eliminating weak spots and ensuring strength and longevity. An opposed-piston design guarantees consistent brake pad grip and wear. These rotors are heat-treated and balanced for optimal performance. The kit includes D.O.T. compliant stainless-steel braided brake lines, which prevent hose expansion under pressure, leading to quicker pedal response and a firmer pedal feel compared to stock rubber lines. This kit is made to order, with an estimated ETA to be provided once the order is submitted to the supplier. While street pads are standard, an upgrade to race pads is available for those prioritizing extreme track conditions. The caliper color and center bell can also be customized with various finishes and options for an additional charge. The product is designated for competition/off-road use unless explicitly stated otherwise by Ksport USA.
