Ksport BKAC010-621SO ProComp Front 6-Piston Big Brake Kit with 12 in. Slotted Floating Rotor

The Ksport BKAC010-621SO ProComp Big Brake Kit is a sophisticated bolt-on brake upgrade engineered to dramatically enhance stopping power and reduce brake fade under sustained high-heat conditions. Designed for easy installation with minimal tools in most applications, this kit requires no vehicle modifications and comes complete with everything needed for a full brake system upgrade.

Aircraft-Grade Billet Caliper Construction:

• Forged one-piece caliper CNC machined from aircraft-quality billet aluminum — not cast or welded
• Differential bore configuration for optimized pad clamping force across the full pad surface
• Weighs just over 5 lbs. each — delivering significant unsprung weight savings over OEM
• Machined-in protection grooves for bridge tube durability
• Aluminum pistons with high-temperature seals for heat resistance and uncompromised operation
• Stainless-steel brake pad wear plates standard on every caliper
• Opposed piston design greatly improves pad wear evenness and caliper rigidity versus OEM

Two-Piece Floating Rotor Design:

• Lightweight 2-piece disc assembly reduces both rotating and unsprung weight
• Full-floating outer disc section shifts slightly as needed for better self-centering in the caliper, lowering brake drag and improving braking consistency
• Floating design eliminates thermal stress warping and disc cupping caused by extreme heat
• Unique slot pattern expels gas and pad debris faster than conventional slotted designs while minimizing brake noise
• Every rotor is heat-treated and precision-balanced before shipment
• Slotted rotors recommended for track and performance driving; cross-drilled rotors recommended for daily street use

Stainless-Steel Braided Brake Lines:

• D.O.T.-compliant stainless-steel braided lines included as standard
• Eliminates hose expansion under pressure for a firmer, more responsive pedal feel versus stock rubber lines

NAOC Ceramic Brake Pads:

• Optimized for street use with occasional track conditions
• Reduces brake dust by 50% or more compared to race pads
• Optimal operating temperature range: 194°F – 1,022°F
• Minimizes noise and rotor wear

All Ksport Big Brake Kits are backed by a 12-month warranty covering manufacturer defects. Caliper color options are available in Orange, Red, Black, and Yellow as standard, with premium anodized and high-polish finishes available as upgrades. Titanium center bell and hardware upgrades are also available for further customization.
