Overview

The Ksport Dualcomp Big Brake Kit is a rear 4-piston caliper system designed for drifting and rally racing. It features a dual caliper solution where 2 pots are used for the foot brake and 2 pots for the handbrake, each running independently. This complete bolt-on system includes calipers, floating brake discs, brake pads, and all necessary hardware.
Show original supplier description
This innovative system utilizes a single 4-pot caliper, intelligently divided with two pots dedicated to the foot brake and the other two for the handbrake, ensuring independent operation for enhanced control. The kit is a complete bolt-on package, designed for straightforward installation and includes everything required: forged, monoblock aluminum calipers, lightweight two-piece slotted rotors (330mm diameter, 32mm width), SC5 Street Brake Pads, stainless steel braided brake lines, and all necessary mounting components and hardware. The handbrake component is crafted from polished titanium for both aesthetic appeal and precise control. The included SC5 Street Pads offer optimal braking performance for street and occasional track use, minimizing dust and rotor wear while operating effectively between 194°F and 1022°F. Customization options are abundant, with calipers available in standard colors like Orange, Red, Black, and Yellow, and premium high-polish finishes including Silver, Gold, and Titanium, as well as Glassy/Hard Anodized colors. Further personalization is possible with over 20,000 custom color finishes. Rotors can also be specified as either slotted or cross-drilled, with cross-drilled recommended for daily drivers due to cooler operation, and slotted for more track-focused applications.
