Description

The Ksport Slimline Big Brake Kit provides a significant upgrade in stopping power and caliper clearance for the BMW M3 (1999-2005). This kit includes 3-piston calipers with 350mm drilled rotors, designed for enhanced heat dissipation, making them recommended for daily driven vehicles. The package also features SC5 Street Pads, which offer optimal braking performance under street and occasional track conditions, reducing dust and noise compared to race pads. Additionally, DOT compliant stainless steel braided brake lines are included to eliminate hose expansion under pressure, resulting in a quicker pedal response and a firmer pedal feel over stock rubber lines. The calipers are made from forged aluminum and can be customized with various painted or high-polish finishes. CNC machined carbon steel caliper brackets ensure a direct bolt-on installation to the vehicle's OEM caliper bracket locations. Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks. The product listing specifically identifies compatibility with BMW M3 models from 1999 to 2005. Fitment can be further confirmed using the vehicle search tool provided on the product page.
