{"product_id":"dualcomp-rear-4-piston-big-brake-kit-4","title":"Dualcomp Rear 4-Piston Big Brake Kit","description":"The Ksport Dualcomp 4-Piston Rear Big Brake Kit (BKBM111-445SO) offers a unique dual-caliper solution engineered for high-performance driving scenarios such as drifting and rally racing. This innovative system utilizes a single 4-pot caliper, with half the pistons dedicated to the primary foot brake and the other half exclusively for the handbrake. Each brake circuit operates independently, providing enhanced control and responsiveness.\n\nThis comprehensive kit is designed as a direct bolt-on upgrade, arriving with everything required for installation: Ksport 4-pot calipers, lightweight two-piece floating brake discs, SC5 street performance brake pads, a polished titanium handbrake cylinder and lever, and all necessary hardware. Customers can select between slotted or cross-drilled rotors, with cross-drilled recommended for daily drivers due to better cooling, and slotted for track use.\n\nBrake pads included are Ksport's NAOC Ceramic pads, optimized for street and occasional track use, offering reduced dust and noise compared to race pads, with an operating temperature range of 194°F - 1022°F. The kit also includes 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. Customization is a key feature, with standard caliper colors (Orange, Red, Black, Yellow) and premium finishes (Silver, Gold, Titanium, Glassy\/Hard Anodized) available, along with over 20,000 custom color options. This brake kit is Formula Drift legal.\n\nKsport Big Brake Kits are built to order, and production and delivery typically take 4-6 weeks.
