Product Details

The Ksport DualComp Big Brake Kit is an all-in-one dual caliper braking solution engineered for drift and rally racing applications. Unlike conventional brake kits, the DualComp system integrates both foot brake and handbrake functions into a single 4-piston caliper — with 2 pistons dedicated to the foot brake and 2 pistons dedicated to the handbrake, each operating independently on its own hydraulic circuit.

Key Features:

  • Dual-Function 4-Piston Caliper: Combines foot brake and handbrake into a single caliper; each circuit operates independently for precise control
  • 14-Inch (356mm) Drilled Floating Rotor: Two-piece design with a 6061-T6 aircraft-grade aluminum center hub reduces rotational mass by up to 50% compared to OEM rotors
  • CNC-Machined Carbon Steel Caliper Brackets: Allows the larger-than-OEM calipers to bolt directly to factory mounting points without vehicle modification
  • Polished Titanium Handbrake Cylinder and Lever: Included as standard for enhanced feel and improved handling control
  • DOT-Compliant Stainless-Steel Braided Brake Lines: Prevents line expansion under pressure for a firmer pedal feel and quicker brake response over stock rubber lines
  • NAOC Ceramic Brake Pads: Optimal operating range of 194°F–1022°F; reduces brake dust by up to 50% compared to race pads with minimal rotor wear
  • Reduced Rotor Warping: Two-piece rotor construction allows the outer iron ring to expand and contract independently from the aluminum center, significantly reducing heat-induced warping
  • Formula Drift Legal: Approved for competition use; suitable for wheels 18 inches and above
  • 12-Month Warranty: All Ksport Big Brake Kits include a standard 12-month warranty covering manufacturer defects

This is a complete bolt-on kit that includes calipers, floating brake disc, brake pads, handbrake hardware, and all required installation hardware. Minimal tools are required and no permanent vehicle modifications are needed in most applications. Note: Compatible with 2WD vehicles only unless otherwise stated.

Easy!

Great service site easy to navigate and parts easy to find great place to shop.

Only place I could find this part. Fast and easy shipping.

Gave one star because I have yet to use the product. Everything so far, delivery and price has been excellent.

Easy checkout! So glad that THMotorsports gives the option for PayPal checkout... makes the process much more hassle-free.

The ordering process was very easy.
