Ksport BKLX230-621SO Procomp Big Brake Kit Front Piston Slotted Floating Rotor - 6 304mm

The Ksport BKLX230-621SO Procomp Big Brake Kit is a sophisticated bolt-on brake upgrade engineered to dramatically enhance stopping power under sustained high-heat conditions. Designed for the front axle with a 6-piston opposed caliper and a 304mm (12 in.) slotted two-piece floating rotor, this kit delivers race-proven braking performance with a straightforward installation requiring minimal tools in most applications.

Caliper Construction:

• CNC machined from a single solid billet of aircraft-grade aluminum — no casting, no welding — for uniform wall thickness and unparalleled structural integrity
• Differential bore, opposed-piston configuration significantly improves pad wear and caliper rigidity over OEM designs
• Lightweight aluminum pistons provide superior heat resistance and consistent operation under extreme temperatures
• High-temperature seals and stainless-steel brake pad wear plates included as standard
• Machined-in protection grooves for the bridge tubes add durability
• Each caliper weighs just over 5 lbs., minimizing unsprung weight

Two-Piece Floating Rotor:

• Full two-piece floating disc assembly reduces both rotating and unsprung weight — Ksport rotors can weigh up to 50% less than OEM rotors of equivalent size
• Floating outer ring shifts slightly as needed for better self-centering in the caliper, lowering brake drag and promoting more even pad application
• Floating design prevents thermal stress from warping the disc or cupping the braking surface under extreme heat
• Unique slotted rotor design rapidly expels gas and pad debris while minimizing braking noise
• Every rotor is heat treated and precision balanced before shipment
• Slotted rotors are recommended for track-focused or high-performance use; cross-drilled rotors are available for daily-driven applications

Stainless-Steel Brake Lines & Pads:

• D.O.T.-compliant stainless-steel braided brake lines are included as standard — they resist expansion under pressure, deliver a firmer pedal feel, and improve response over OEM rubber lines
• Included NAOC Ceramic brake pads offer optimal performance for street and occasional track use, with operating temperatures between 194°F and 1,022°F
• Ceramic compound reduces brake dust by 50% or more compared to race pads and minimizes rotor wear and noise

Hardware & Brackets:

• CNC machined carbon steel caliper brackets included — engineered to bolt directly to the OEM caliper mounting location without vehicle modifications
• Kit includes calipers, floating brake disc, brake pads, brake lines, and all required hardware

All Ksport Big Brake Kits are covered by a 12-month manufacturer's defect warranty and are compatible with all OEM ABS systems. Caliper finish options include standard painted colors (orange, red, black, yellow) as well as premium anodized and high-polish upgrades.
