Show original supplier description

This innovative system features a single 4-piston caliper, intelligently split to operate the foot brake and the handbrake independently, ensuring optimal control and performance. Constructed with CNC machined carbon steel caliper brackets, this kit ensures a direct bolt-on installation to your OEM caliper bracket locations. The kit includes a polished titanium handbrake cylinder and lever for enhanced feel and aesthetics, along with SC5 street pads designed for optimal performance in street and occasional track conditions. These pads offer reduced dust and noise compared to race pads, with an optimal operating temperature range of 194°F - 1022°F. For improved pedal response and feel, the kit incorporates D.O.T. compliant stainless steel braided brake lines, which prevent expansion under pressure. You can choose between slotted or cross-drilled rotors; cross-drilled are recommended for daily drivers due to cooler running temperatures, while slotted rotors are recommended for track use. This kit is built to order, with production and delivery typically taking 4-6 weeks. This big brake kit is Formula Drift legal and designed for 18-inch wheels or larger. It is compatible with 2WD vehicles only. The Ksport Dualcomp Big Brake Kit fits 1991-1995 Toyota MR2 models. Please verify fitment with your specific vehicle before ordering.
