Supercomp 8-Piston 421mm Front Big Brake Kit

The Ksport Supercomp Front Big Brake Kit is engineered to deliver superior stopping power for the BMW E71 X6. This kit includes massive 421mm (16.6-inch) diameter, 36mm thick rotors that are available in either cross-drilled or slotted designs, with cross-drilled recommended for daily driven vehicles and slotted for track use. Complementing the rotors are 8-piston calipers forged from aircraft-quality billet aluminum, featuring differential bore configurations and larger pistons for immense stopping force. The kit incorporates a 2-piece floating disc assembly, which minimizes weight and prevents thermal stresses from warping the disc. Standard equipment includes Ksport SC5 Street Pads, which offer optimal performance under street and occasional track conditions, reducing brake dust and noise compared to race pads. For more extreme use, Ksport RC5 Race Pads, made from carbon metallic, are available as an option. Stainless steel braided brake lines are also included, improving pedal feel and response. The SuperComp kit is made to order and is non-refundable. Customization options include various caliper colors and optional upgrades for brake pads, center bells, and rotor styles, allowing for a personalized braking system. This big brake kit is specifically designed for the BMW E71 X6 models from 2008-2014, including variants such as the xDrive35i (N54 3.0L, N55 3.0L), xDrive50i (N63 4.4L), and the X6 M (S63 4.4L).
