Ksport BKTY261-621SO Floating Rotor Big Brake Kit Piston Caliper - 4/6/8

The Ksport BKTY261-621SO is a high-performance floating rotor big brake kit engineered to deliver maximum stopping power with significantly reduced brake fade. Available with 4, 6, or 8 piston caliper options, this kit is built for drivers who demand superior braking performance on the street or track.

Ksport's innovative 2-piece floating disc assembly minimizes both rotating and unsprung weight while allowing the rotor to expand and contract independently under extreme heat. This floating design prevents thermal stress from warping the disc or cupping the braking surface — a critical advantage during high-performance driving.

Key Features:

• Lightweight One-Piece Caliper: CNC machined from aircraft-quality billet aluminum in a differential bore configuration, weighing just over 5 lbs. each
• Opposed Piston Design: Dramatically improves pad wear and caliper rigidity compared to OEM designs
• Aluminum Pistons: Reduce overall caliper weight while maintaining strength and heat resistance
• High-Temperature Seals: Engineered to maintain performance under sustained extreme braking conditions
• Stainless-Steel Brake Pad Wear Plates: Standard on every caliper for extended pad and caliper longevity
• Machined Bridge Tube Protection Grooves: Integrated into each caliper for added structural durability
• Stainless-Steel Brake Lines: Prevent hose expansion under pressure for a firm, consistent pedal feel
• Unique Slot Design: Rapidly expels gas and pad debris while reducing braking noise more effectively than conventional slot patterns
• Heat Treated & Balanced Rotors: Every rotor is heat treated and dynamically balanced before shipment for optimum performance and longevity
• Easy Installation: Designed for straightforward fitment requiring minimal tools in most applications

Rotor Style Guide:

• Cross-Drilled Rotors — Run cooler and are recommended for daily-driven vehicles
• Slotted Rotors — Best suited for track-focused applications with more aggressive use

The Ksport BKTY261-621SO big brake kit is a complete, race-proven upgrade that continuously cools and refreshes the brake pad surface under repeated hard stops, making it an ideal solution for performance enthusiasts seeking a direct replacement or upgrade over factory braking components.
