Supercomp 400x36mm 8-Piston Big Brake Kit

The Ksport Supercomp Big Brake Kit represents a significant upgrade in stopping power for your vehicle, specifically designed for the Volvo XC40. This advanced braking system integrates new technology to drastically reduce brake fade and continually cool and refresh the brake pad surface during intense use. At the heart of the SuperComp system is an extreme lightweight caliper, forged from aircraft-quality billet aluminum. This caliper features a differential bore configuration with significantly larger pistons than Ksport's ProComp calipers, contributing to massive stopping power. Standard features include aluminum pistons, high-temperature seals, titanium brake pad retainer clips, and stainless-steel brake pad wear plates. The opposed piston design enhances pad wear and caliper rigidity, while the included stainless-steel brake lines resist expansion under pressure. Due to the caliper's size, each unit utilizes four brake pads. The kit incorporates a 2-piece floating disc assembly, which reduces both rotating and unsprung weight. This design also mitigates thermal stresses from extreme heat, preventing disc warping and surface cupping. The rotors feature a unique slot design that reduces braking noise and efficiently expels gas and pad debris. For daily driven vehicles, cross-drilled rotors are recommended for cooler operation, while slotted rotors are suggested for more track-oriented use. This particular kit comes with 400x36mm cross-drilled rotors and includes Ksport SC5 Street Pads, engineered with NAOC ceramic for optimal performance between 194°F – 1022°F, offering reduced dust, noise, and rotor wear compared to race pads. All Ksport big brake kits are made to order and are non-refundable. While UroTuning does not explicitly list fitment vehicles for this item, Ksport generally engineers these kits for direct bolt-on application with vehicle-specific caliper brackets.
