Ksport BKSB100-621SO Big Brake Kit Floating Rotor 4, 6, or 8 Piston Caliper

The Ksport BKSB100-621SO Big Brake Kit delivers a substantial upgrade in stopping power over OEM braking systems. Engineered with advanced brake technology, this kit significantly reduces brake fade while continuously cooling and refreshing the brake pad surface during repeated braking events. The bolt-on design requires minimal tools and no vehicle modifications in most applications.

Billet Aluminum Caliper Construction:

• CNC machined from a single solid billet of aircraft-grade aluminum — not cast or welded
• Available in 4, 6, or 8 piston configurations to match your braking demands
• Differential bore opposed-piston design improves pad wear evenness and caliper rigidity over OEM
• Weighs just over 5 lbs. each — up to 4x lighter than comparable stock calipers
• Machined-in protection grooves for bridge tubes
• Aluminum pistons with high-temperature seals for superior heat resistance
• Stainless steel brake pad wear plates standard on every caliper

Two-Piece Floating Rotor Assembly:

• Floating outer rotor section shifts slightly to self-center in the caliper, reducing brake drag and improving application consistency
• Two-piece disc construction reduces both rotating and unsprung weight
• Floating design prevents thermal stresses from warping the disc or cupping the braking surface under extreme heat
• Every rotor is heat treated and precision balanced before shipment
• Unique slot pattern expels gas and pad debris faster than conventional slot designs while minimizing braking noise
• Available in Cross Drilled (recommended for daily-driven vehicles — runs cooler) or Slotted (recommended for track and performance use)

DOT-Compliant Stainless Steel Braided Brake Lines:

• Eliminate hose expansion under pressure for a firmer, more responsive pedal feel
• Provide quicker pedal response compared to stock rubber lines

NAOC Ceramic Brake Pads Included:

• Optimal operating range: 194°F – 1,022°F for reliable street and occasional track performance
• Reduce brake dust by 50% or more versus race pads
• Minimize noise and rotor wear

All Ksport Big Brake Kits are covered by a 12-month warranty against manufacturer defects. OEM ABS systems remain fully functional with this brake kit installed. Note: Ksport Big Brake Kits are built to order.
