Description

The Ksport Slimline Big Brake Kit is a high-performance braking upgrade engineered for the BMW 6 Series, specifically for model years 2012-2015. This kit features robust 350mm x 22mm slotted rotors paired with a compact 3-piston slimline caliper, designed to provide superior stopping power and a significant improvement over the factory braking system. Constructed with performance in mind, the kit incorporates stainless steel brake lines. These lines are crucial for enhancing braking feel, as they resist expansion under pressure, unlike stock rubber lines. This results in a quicker pedal response and a firmer pedal feel, allowing for more precise modulation of braking force. The slotted rotors are recommended for vehicles that see more track time, as they help to dissipate heat more effectively than drilled rotors. Ksport Big Brake kits are built to order, so please allow 4-6 weeks for production and delivery. The company emphasizes that fitment should always be confirmed before ordering. If fitment is confirmed by their sales team and the product still does not fit, they will accept returns with no restocking fees, provided the item is in like-new condition. Fitment is confirmed for various 2012-2015 BMW 640i and 650i models, including Base, Gran Coupe, and xDrive trims.
