Ksport BKVO010-621SO ProComp Front Big Brake Kit 12in Slotted Floating Rotor

The Ksport BKVO010-621SO ProComp Big Brake Kit is a sophisticated bolt-on brake upgrade engineered to dramatically enhance stopping power under sustained high-heat conditions. Featuring advanced brake technology throughout, this system significantly reduces brake fade while continuously cooling and refreshing the pad surface during braking — making it equally at home on the street or the track.

Aircraft-Grade Billet Aluminum Calipers

Each caliper is CNC-machined from a single solid billet of aircraft-grade aluminum — not cast or welded — delivering perfectly uniform wall thickness and strength throughout the entire caliper body. This one-piece construction provides unparalleled rigidity and complete freedom from corrosion. Calipers weigh just over 5 lbs. each and feature a differential bore configuration, machined-in bridge tube protection grooves, aluminum pistons for superior heat resistance, high-temperature seals, and stainless-steel brake pad wear plates as standard. The opposed piston caliper design significantly improves pad wear evenness and caliper rigidity compared to OEM designs.

Two-Piece Floating Rotor Design

The 12-inch (304mm) two-piece floating disc assembly reduces both rotating and unsprung weight. The floating outer rotor section is engineered to shift slightly under load, allowing better self-centering within the caliper — lowering brake drag and improving performance through more even pad application. Critically, the floating disc design prevents thermal stresses from extreme heat warping the disc or cupping the braking surface. Every rotor is heat treated and balanced before shipment to ensure optimal, consistent performance.

Rotor Style Options

• Slotted Rotors: The unique slot pattern rapidly expels gas and pad debris faster than conventional designs while reducing braking noise — ideal for track-focused use
• Cross-Drilled Rotors: Run cooler than slotted rotors and are recommended for predominantly street-driven vehicles

DOT-Compliant Stainless-Steel Braided Brake Lines

Stainless-steel braided brake lines are standard and fully DOT compliant. These lines eliminate hose expansion under pressure, delivering a quicker pedal response and firmer pedal feel compared to stock rubber lines.

CNC Carbon Steel Caliper Brackets

All Ksport big brake kits include CNC-machined carbon steel caliper brackets that allow the oversized calipers to bolt directly to the OEM caliper bracket location — no vehicle modifications required in most applications.
