Description

This kit is designed as a sophisticated, bolt-on solution to enhance brake power, particularly during sustained high-heat situations. They feature aluminum pistons, which offer better heat resistance compared to standard materials, maintaining uncompromised operation even under stress. For customization, you can choose between slotted rotors, recommended for track use, or cross-drilled rotors, better suited for daily driven vehicles. The kit comes with CNC-machined carbon steel caliper brackets that facilitate direct bolt-on mounting to your OEM caliper bracket location, accommodating the larger Ksport calipers. Included are NAOC Ceramic SC5 Street Pads, optimized for street and occasional track use, offering reduced brake dust (by 50% or more) and noise compared to race pads, with an optimal operating temperature range of 194°F - 1022°F. Customization options are extensive, with calipers available in standard painted colors like Orange, Red, Black, and Yellow, and premium high-polish finishes including Silver, Gold, Titanium, and Glassy/Hard Anodized Colors. Over 20,000 custom color finishes are also available. Ksport Big Brake kits are built to order, and production and delivery typically take 4-6 weeks. Fitment is specifically listed for 2014-2018 Mini Cooper S models. If fitment issues arise, Ksport and its retailers work to resolve them, potentially waiving restocking fees if a fitment recommendation from their sales team proves incompatible.
