Description

The Ksport Slimline Front Big Brake Kit (BKBM251-342CO) is engineered to provide a significant upgrade in stopping power and performance for your BMW F31 3-Series Wagon. The calipers are constructed from a lightweight forged one-piece billet of aerospace-quality aluminum, ensuring strength and eliminating weak spots. They feature an opposed-piston design for consistent brake pad grip and wear, and are equipped with high-temperature seals, titanium retainer clips, and stainless-steel wear plates. This design also minimizes the risk of warping due to heat buildup. This kit includes Ksport's SC5 Street Pads, which offer optimal braking performance for street and occasional track use, with reduced dust and noise compared to race pads. The system also features D.O.T compliant stainless-steel braided brake lines for a firmer pedal feel and quicker response. Customization options are available for caliper color, including standard painted colors and premium high-polish finishes, as well as upgrades to titanium center bells and hardware or twin-color anodized center bells. All Ksport Big Brake Kits come with a 12-month warranty covering manufacturer defects. Please note that this product is made to order and is non-refundable once the order is placed. The image shown is for representational purposes only, and the actual product may vary slightly.
