Slimline 3-Piston Front Big Brake Kit w/ 350mm Drilled Rotors

The Ksport Slimline Big Brake Kit offers a significant upgrade for the braking system of your Audi B9 A4. Its opposed-piston design ensures consistent brake pad grip and wear, while high-temperature seals and titanium retainer clips handle demanding conditions. The caliper utilizes a two-piece rotor system with 350mm x 22mm drilled rotors, chosen for their ability to run cooler than slotted rotors, making them ideal for daily driven vehicles seeking enhanced stopping power. Key components of the Slimline kit include the forged monoblock calipers, floating brake discs, brake pads (SC5 Street pads included with an option to upgrade to RCI Race Pads), and all necessary hardware for a direct bolt-on installation. Its construction allows the outer rotor section to expand and contract independently, minimizing warping due to heat. Ksport emphasizes the Slimline caliper's design, which is based on OEM single-side floating piston caliper thickness, allowing it to fit most factory wheels or wheels with limited caliper clearance. This kit comes standard with D.O.T. compliant stainless-steel braided brake lines, which help prevent line expansion under pressure, leading to a quicker pedal response and a firmer pedal feel compared to stock rubber lines. The kit is made to order and is non-refundable. Customization options are available for caliper color, including various standard and premium finishes, as well as rotor types (drilled or slotted) and center bell upgrades. A 12-month limited warranty covers manufacturer defects.
