Description

The Ksport Procomp Big Brake Kit is engineered to significantly enhance stopping power for the Mini Cooper R50 Hardtop (2002-2006). This advanced system replaces your factory brakes with a high-performance upgrade, featuring a sophisticated 6-piston caliper design. The calipers are crafted from a solid billet of aircraft-quality aluminum, ensuring both light weight and exceptional strength, with a unique differential bore configuration and machined protection grooves. The kit utilizes 304mm diameter, 28mm wide slotted rotors in a 2-piece assembly with an aluminum center. This design reduces rotational and unsprung weight, leading to quicker braking response and shorter stopping distances. The 2-piece construction also minimizes rotor warpage by allowing for less restricted expansion and contraction. Stainless steel brake lines are included to prevent expansion under high temperatures and pressures, providing a firmer pedal feel and faster response. Ksport also offers choices between SC5 Street pads for daily driving or RC1 Race Pads for track conditions. Slotted rotors are recommended for track use as their grooves help to dissipate heat, dust, and gases, while drilled rotors are suggested for daily-driven vehicles. All Ksport big brake kits come with a 12-month warranty against manufacturer defects.
