Description

The Ksport DualComp Big Brake Kit provides a sophisticated, bolt-on solution to significantly upgrade your vehicle's braking capabilities. This kit is engineered with a unique Dual Caliper system, featuring a single 4-piston caliper designed to manage both the primary foot brake and the handbrake independently. Two pistons engage for standard braking, while the other two are reserved for the handbrake, offering enhanced control and performance. This complete kit includes everything needed for a direct installation: high-performance calipers, floating brake discs with a 356mm rotor size, and SC5 Street Pads. The included stainless-steel braided brake lines are crucial for preventing line expansion under pressure, resulting in quicker pedal response and a firmer pedal feel compared to stock rubber lines. You can choose between slotted or cross-drilled rotors; slotted rotors are recommended for track use, while cross-drilled rotors are better suited for daily driving due to their superior cooling capabilities. The Ksport DualComp Big Brake Kit is specifically designed for the BMW 5 Series models from 1997 to 2003. Fitment includes various trims such as the 525i, 528i, 530i, and 540i across these model years. It's important to confirm exact fitment for your specific vehicle configuration, as Ksport big brake kits are built to order and may have a production lead time of 4-6 weeks. Fitment Industries emphasizes confirming compatibility before ordering. If your vehicle is not explicitly listed, it's recommended to contact their team. In cases where Fitment Industries' sales team confirms fitment and the product still doesn't fit, they will facilitate a return with no restocking fees, provided the item remains in like-new condition. However, customers are advised that most orders may be subject to restocking or cancellation fees, especially if initiated later in the processing or shipping stages.
