Supercomp 8-Piston 421mm x 36mm Orange Billet Aluminum Big Brake Kit

The Ksport Supercomp Big Brake Kit represents an extreme upgrade in stopping power for your BMW 3 Series E46 (1999-2005). The kit includes Ksport's SuperComp 8-piston calipers, which are machined from aircraft-quality billet aluminum, feature a differential bore configuration for improved pad wear, and come standard with aluminum pistons, high-temperature seals, and stainless steel wear plates. The opposed piston design enhances caliper rigidity over OEM components. The kit incorporates 2-piece floating rotors measuring 421mm x 36mm. The floating design reduces rotational mass and helps prevent rotor warping under extreme heat. The unique slot design on the rotors aids in reducing braking noise and efficiently expels gas and pad debris. Ksport recommends slotted rotors for vehicles with significant track use. This specific kit comes with the rotors in a slotted configuration and features orange calipers. The kit includes replacement calipers, rotors, pads, stainless steel brake lines, and all related hardware. Note that this kit is specifically designed for the BMW 3 Series E46 models from 1999-2005, with a fitment note indicating compatibility for 330 models with the OEM 282mm front rotor. It is important to verify fitment details for your specific vehicle configuration. Ksport offers different pad compounds, with SC5 Street pads for daily driving and RC1 Race Pads for extreme track conditions. All Ksport big brake kits come with a 12-month warranty against manufacturer defects.
