Ksport BKAC021-621CO Floating Rotor Big Brake Kit | 4, 6, or 8 Piston Caliper

The Ksport BKAC021-621CO is a high-performance big brake kit featuring a two-piece floating rotor assembly with your choice of 4, 6, or 8 piston caliper configuration. Engineered to deliver maximum stopping power while significantly reducing brake fade, this system continuously cools and refreshes the brake pad surface under repeated hard braking.

Caliper Features:

• Extreme lightweight one-piece opposed piston caliper in differential bore configuration
• CNC machined from aircraft-grade billet aluminum
• Weighs just over 5 lbs. each for significant unsprung weight reduction
• Machined-in protection grooves for bridge tube durability
• Aluminum pistons with high-temperature seals for reliable performance under extreme heat
• Stainless steel brake pad wear plates standard on every caliper
• Opposed piston design improves pad wear evenness and caliper rigidity over OEM designs
• Stainless steel brake lines resist expansion under pressure for consistent pedal feel

Floating Rotor Features:

• Two-piece disc assembly reduces both rotating and unsprung weight
• Floating disc design eliminates thermal stress warping and prevents cupping of the braking surface under extreme heat
• Unique slot design expels gas and pad debris faster than conventional slot patterns while reducing braking noise
• Every rotor is heat treated and balanced before shipment for consistent, optimized performance

Rotor Style Notes:

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

Designed for straightforward installation with minimal tools required in most applications, the Ksport big brake kit is an ideal upgrade for drivers seeking superior braking performance, reduced fade, and long-term pad and rotor longevity.
