Description

The Ksport Supercomp Front Big Brake Kit is engineered to deliver unparalleled stopping power for your Audi B6 S4. This kit integrates advanced brake technology to minimize brake fade and ensure consistent performance, even under demanding conditions. The SuperComp caliper, forged from aircraft-quality billet aluminum, is exceptionally lightweight yet robust, featuring differential bore configurations, larger pistons than ProComp calipers, and aluminum pistons with high-temperature seals. The opposed piston design enhances pad wear and caliper rigidity, while stainless-steel braided brake lines improve pedal feel and response. The 2-piece floating disc assembly reduces both rotating and unsprung weight, preventing thermal stresses from warping the disc. The unique rotor slot design helps dissipate gas and pad debris, while cross-drilled rotors are recommended for daily driven vehicles to maintain cooler temperatures. Standard with the kit are Ksport SC5 Street Pads, made from NAOC ceramic material, offering optimal braking performance for street and occasional track use with reduced dust, noise, and rotor wear. For more aggressive track use, optional Ksport RC5 Race Pads (carbon metallic) are available. This kit is specifically designed for the Audi S4 B6 models from 2003-2005 with the 4.2L V8 engine. As this is a made-to-order product, it is non-refundable once the order is placed.
