Dual Caliper System with Floating Brake Disc and Hardware

The Ksport Dualcomp 4-Piston Rear Big Brake Kit is engineered to provide enhanced braking performance for drift and rally racing. This advanced system utilizes a unique Dual Caliper setup with a single 4-piston caliper, ingeniously splitting function between the foot brake (two pistons) and the handbrake (two pistons), each operating on independent circuits for superior control and reliability. The complete bolt-on kit includes everything needed for installation: calipers, floating brake discs, SC5 Street Pads, and all required hardware. The kit features a 356mm rotor diameter and comes with D.O.T. compliant stainless-steel braided brake lines, which resist expansion under pressure for a quicker pedal response and a firmer pedal feel compared to stock rubber lines. For customization, customers can choose between Cross Drilled rotors, recommended for daily driven vehicles due to their cooler running temperatures, or Slotted rotors, better suited for track use. The caliper brackets are CNC machined from Carbon Steel to ensure a direct bolt-up to OEM caliper bracket locations. This system also includes a polished Titanium handbrake cylinder and lever for an enhanced look and feel. Calipers are available in standard colors like Orange, Red, Black, and Yellow, with premium finish options and over 20,000 custom color choices also available. Ksport Big Brake kits are built to order, with production and delivery typically requiring 4-6 weeks. The specific trim and engine fitment for this kit is for Subaru Impreza WRX models from 2008-2021, including STI variants and trims such as '6 Man' and 'Base'.
