Ksport BKSB200-611SO Procomp Big Brake Kit Front 6 Piston 11.3 in. Slotted Floating Rotor

The Ksport Procomp Big Brake Kit (BKSB200-611SO) is a sophisticated bolt-on brake upgrade engineered to deliver superior stopping power under sustained high-heat conditions. Designed for easy installation with minimal tools and no vehicle modifications required in most applications, this kit is a direct performance upgrade over factory brake systems.

Billet Aluminum Calipers

Each caliper is CNC machined from a single solid billet of aircraft-grade aluminum, providing a lightweight one-piece construction that offers unparalleled strength and resistance to corrosion. The differential bore opposed-piston design significantly improves pad wear and caliper rigidity compared to OEM units. Machined-in protection grooves safeguard the bridge tubes, and each caliper weighs just over 5 lbs. Standard caliper configurations include 4, 6, or 8 piston options to suit a range of performance requirements.

Key Caliper Features:

• CNC machined from aircraft-grade billet aluminum — one-piece construction
• Differential bore, opposed-piston design for improved pad wear and rigidity
• Aluminum pistons for superior heat resistance and consistent operation
• High-temperature seals rated for extreme braking conditions
• Stainless-steel brake pad wear plates standard on every caliper
• Machined-in protection grooves for bridge tube durability
• Available in 4, 6, or 8 piston configurations

2-Piece Floating Rotor Assembly

This kit features a 2-piece floating disc assembly measuring 11.3 inches (286mm) in diameter with a slotted rotor surface. The floating design allows the outer rotor section to shift slightly as needed, enabling better self-centering within the caliper, reducing brake drag, and promoting more even pad application. Critically, the floating design prevents thermal stresses from warping the disc or cupping the braking surface under extreme heat — a common failure point of solid one-piece rotors.

Rotor Features:

• 11.3 in. (286mm) diameter slotted rotor
• 2-piece floating disc assembly reduces both rotating and unsprung weight
• Unique slot pattern expels gas and pad debris faster than conventional designs
• Floating outer section allows self-centering for reduced brake drag
• Every rotor is heat treated and balanced before shipment
• Slotted style recommended for performance and track-oriented driving

Stainless-Steel Braided Brake Lines

DOT-compliant stainless-steel braided brake lines are included and eliminate hose expansion under pressure, delivering a firmer pedal feel and quicker pedal response compared to stock rubber lines.

What's Included:

• Replacement calipers (4, 6, or 8 piston — per configuration)
• Slotted floating brake rotors
• Brake pads
• Stainless-steel braided brake lines
• All required installation hardware

All Ksport Big Brake Kits are backed by a 12-month warranty covering manufacturer defects. OEM ABS systems remain fully functional with this upgrade. Note: Ksport Big Brake Kits are built to order.
