Description

The Ksport Supercomp Big Brake Kit offers enhanced stopping power for your Audi B9 A4. This front brake system features a massive 356mm x 32mm rotor diameter and an 8-piston caliper, significantly larger than OEM components. The SuperComp caliper is forged from aircraft-quality billet aluminum, weighing just over 7 lbs each, and incorporates differential bore configuration and larger pistons for superior performance. Each kit includes a 2-piece floating disc assembly, which reduces weight and prevents thermal stresses from warping the disc or cupping the braking surface. The unique slot design on the rotor minimizes braking noise and expels debris faster, while cross-drilled rotors are recommended for daily driven vehicles as they tend to run cooler. Stainless steel braided brake lines are standard, improving pedal feel and response. This kit comes standard with Ksport SC5 Street Pads, designed for optimal braking performance under street and occasional track conditions. An option for Ksport RC5 Race Pads, suitable for extreme track use, is also available. The calipers require 4 brake pads each due to their substantial size. The kit includes CNC-machined carbon steel caliper brackets for direct bolt-on installation. All Ksport Big Brake Kits are made-to-order and are non-refundable. They come with a 12-month limited warranty covering manufacturer defects. This kit is specifically designed for the Audi B9 and B9.5 A4 models with the 2.0T engine and FWD configuration, covering model years 2017-2025.
