Big Brake Kit with Slotted Rotors

This kit features an extreme lightweight, one-piece caliper, CNC machined from aircraft-quality billet, weighing just over 5 lbs. It incorporates differential bore configuration, machined protection grooves for bridge tubes, aluminum pistons, high-temperature seals, and stainless-steel brake pad wear plates. The opposed piston caliper design offers improved pad wear and greater caliper rigidity compared to OEM designs. The kit includes stainless-steel brake lines designed to prevent expansion under pressure and a 2-piece disc assembly that reduces both rotating and unsprung weight. For applications with a floating disc option, it mitigates thermal stresses from extreme heat, preventing disc warping and surface cupping. The rotors feature a unique slot design that not only reduces braking noise but also expels gas and pad debris more efficiently than conventional designs. Every rotor is heat-treated and balanced for optimal performance. This specific kit, BKAU098-652SO, includes 380 x 32mm slotted rotors and a 6-piston caliper. Slotted rotors are recommended for vehicles that experience more track use than daily driving, offering improved cooling and debris expulsion. Please verify fitment for your specific Audi A3 year and trim.
