Description

The Ksport Slimline Big Brake Kit offers a significant upgrade in braking performance for vehicles requiring enhanced stopping power. This kit includes 350mm, two-piece slotted rotors and 3-piston calipers, specifically designed to address the common issue of aftermarket big brake kits not fitting with aggressive wheel fitments. Ksport developed the Slimline caliper to have a thickness comparable to OEM single-piston calipers, ensuring compatibility with most factory wheels or those with very limited brake caliper clearance. The kit utilizes SC5 Street brake pads for a balance of performance and daily drivability. The stainless steel braided brake lines are included to replace stock rubber lines, which helps prevent expansion under pressure, leading to a quicker pedal response and a firmer pedal feel. The two-piece rotor design contributes to reduced weight and improved heat dissipation. Ksport big brake kits are built to order, with a typical production and delivery lead time of 4-6 weeks. This specific kit is designed for the 2016-2018 Mini Cooper S models. As with all automotive components, it is recommended to confirm fitment for your specific vehicle before ordering to avoid potential fitment issues. Fitment Industries' return policy notes that while they strive for customer satisfaction, returns may be subject to restocking fees unless the error is on their part, such as a mis-recommendation from their sales team regarding fitment.
