Ksport BKIN420-841SO Floating Rotor Big Brake Kit with 4, 6, or 8 Piston Caliper

The Ksport BKIN420-841SO Big Brake Kit delivers serious stopping power through advanced brake technology engineered to reduce brake fade while continuously cooling and refreshing the brake pad surface under hard braking. Designed for straightforward installation requiring minimal tools in most applications, this kit is a complete upgrade over factory braking systems.

Lightweight One-Piece Caliper Design:

• Available in 4, 6, or 8 piston configurations to suit your performance needs
• CNC machined from aircraft-grade billet aluminum in a differential bore configuration
• Weighs just over 5 lbs. each for reduced unsprung weight
• Machined-in protection grooves for the bridge tubes
• Aluminum pistons with high-temperature seals for heat resistance
• Stainless-steel brake pad wear plates included as standard
• Opposed piston caliper design improves pad wear and caliper rigidity over OEM

2-Piece Floating Rotor Assembly:

• 2-piece disc construction reduces both rotating and unsprung weight
• Floating disc design prevents thermal stress warping and eliminates braking surface cupping under extreme heat
• Unique slot pattern rapidly expels gas and pad debris while significantly reducing braking noise
• Every rotor is heat treated and dynamically balanced before shipment for consistent, reliable performance
• Stainless-steel brake lines resist expansion under pressure for a firm, responsive pedal feel

Rotor Style Guide:

• Cross-drilled rotors — Run cooler and are recommended for daily-driven street vehicles
• Slotted rotors — Recommended for vehicles with heavier track or performance use

The Ksport big brake kit is a premium brake upgrade built for drivers who demand maximum stopping performance. Whether on the street or the track, this system provides enhanced braking power, improved pedal feel, and long-term durability through high-quality materials and precision engineering.
