Show original supplier description
The Ksport Slimline Big Brake Kit provides a significant braking performance upgrade for the Audi B5 S4. This front brake system is engineered with a focus on both performance and ease of installation, featuring a lightweight forged one-piece caliper with a 3-piston configuration. The kit includes 350mm x 22mm rotors, designed to offer enhanced stopping power and fade resistance for both street and track use. The calipers are constructed from aerospace-grade aluminum billets, ensuring exceptional strength and even thickness to prevent fracturing, warping, and failure. They are equipped with high-temperature seals, titanium retainer clips, and stainless-steel wear plates. These rotors are heat-treated and balanced for optimal performance, with cross-drilled options recommended for daily driven vehicles due to their cooler operation. Ksport's Slimline caliper design is based on the thickness of OEM single-side floating piston calipers, allowing for easier installation with minimal tools and no vehicle modifications required in most applications. The kit comes complete with calipers, floating brake discs, brake pads (SC5 Street Pads standard, with an option to upgrade to RCI Race Pads), and all necessary hardware. Stainless-steel braided brake lines are also included, providing a quicker pedal response and firmer pedal feel. This kit is made to order, and an estimated time of arrival will be provided after the order is submitted to the supplier. Customization options are available for caliper color, including standard painted colors and premium high-polish finishes, as well as twin-color anodized center bells and titanium center bell upgrades. All Ksport Big Brake Kits include a 12-month limited warranty against manufacturer defects.
