Ksport BKSB030-621CO Floating Brake Rotor Big Brake Kit or Piston Caliper Options - with 4 6 8

The Ksport BKSB030-621CO is a high-performance floating rotor big brake kit engineered to deliver maximum stopping power with superior heat management and reduced brake fade. Available with 4, 6, or 8 piston caliper options, this system is designed for enthusiasts who demand professional-grade braking performance.

Caliper Design & Construction:

• Extreme lightweight one-piece CNC machined caliper crafted from aircraft-grade billet aluminum
• Differential bore configuration for optimized pad contact and even wear
• Each caliper weighs just over 5 lbs. for significant unsprung weight reduction
• Machined-in protection grooves for bridge tube durability
• Opposed piston design improves pad wear and caliper rigidity over OEM
• Aluminum pistons with high-temperature seals and stainless-steel brake pad wear plates standard on every caliper

Rotor Design & Technology:

• 2-piece floating disc assembly reduces both rotating and unsprung weight
• Floating disc design prevents thermal stress warping and braking surface cupping under extreme heat
• Unique slot design expels gas and pad debris faster than conventional slotted rotors, greatly reducing brake noise
• Every rotor is heat treated and balanced before shipment for consistent, reliable performance
• Cross-drilled rotors run cooler — recommended for daily-driven vehicles
• Slotted rotors recommended for track-oriented use

Brake Lines & System Features:

• Stainless-steel braided brake lines eliminate expansion under pressure for a firm, consistent pedal feel
• Continuously cools and refreshes the brake pad surface during braking to combat fade
• Designed for straightforward installation with minimal tools required in most applications

The Ksport BKSB030-621CO big brake kit is a complete, track-proven braking upgrade that combines lightweight materials, advanced thermal engineering, and rigid caliper construction to deliver confident, fade-free stopping power in both street and performance driving environments.
