Ksport BKIN420-853SO SuperComp Big Brake Kit with Floating Disc Assembly

The Ksport SuperComp Big Brake Kit (BKIN420-853SO) delivers exceptional stopping power with advanced brake technology engineered to minimize brake fade and continuously cool and refresh pad surfaces during heavy braking. Designed for straightforward installation with minimal tooling required in most applications, this kit represents the pinnacle of Ksport's brake system lineup.

At the heart of the system is Ksport's extreme lightweight SuperComp caliper, machined from aircraft-quality billet aluminum in a differential bore configuration. Featuring significantly larger pistons than Ksport's ProComp calipers, each caliper weighs just over 7 lbs. and includes machined-in protection grooves for the bridge tubes. Four brake pads per caliper are standard, along with aluminum pistons, high-temperature seals, and stainless steel brake pad wear plates. The opposed piston caliper design improves pad wear consistency and caliper rigidity compared to OEM designs.

Key Features:

• Aircraft-quality billet aluminum SuperComp calipers in differential bore configuration
• Larger piston size versus ProComp series for enhanced clamping force
• Opposed piston caliper design for improved pad wear and rigidity
• Four brake pads standard per caliper
• Aluminum pistons with high-temperature seals
• Stainless steel brake pad wear plates and braided stainless steel brake lines
• 2-piece floating disc assembly reduces rotating and unsprung weight
• Floating disc design prevents thermal warping and braking surface cupping
• Unique slot design expels gas and pad debris faster than conventional slots
• Every rotor is heat treated and balanced prior to shipment

The 2-piece floating disc assembly is standard on all SuperComp systems, reducing both rotating and unsprung weight while preventing thermal stress from extreme heat from warping the disc or cupping the braking surface. The proprietary slot geometry significantly reduces braking noise and evacuates gas and debris more efficiently than conventional slotted designs.

Stainless steel brake lines eliminate hose expansion under pressure for a firm, consistent pedal feel. Cross-drilled rotors run cooler and are recommended for daily-driven vehicles, while slotted rotors are better suited for track-focused applications with more aggressive use.
