Description

The Ksport Dualcomp 4 Piston 356mm Rear Big Brake Kit offers an advanced braking solution for performance enthusiasts, particularly those in drifting and rally racing. This kit introduces a novel dual-caliper system, where a single 4-piston caliper is ingeniously split, with two pistons dedicated to the primary foot brake and the other two independently controlling the handbrake function. This innovative design ensures robust stopping power and precise control. The kit is supplied with Ksport's SC5 Street Pads, which provide excellent performance under street and occasional track conditions, offering reduced dust and noise. Furthermore, the kit incorporates D.O.T compliant stainless-steel braided brake lines that eliminate expansion under pressure, resulting in a quicker pedal response and a firmer pedal feel than stock rubber lines. The handbrake mechanism features a polished titanium cylinder and lever for enhanced aesthetics and control. The calipers are available in standard painted colors (Orange, Red, Black, Yellow) with options for premium high-polish finishes (Silver, Gold, Titanium) and extensive custom color choices. Ksport Big Brake kits are built to order, and customers should anticipate a production and delivery lead time of 4-6 weeks. Please note that Ksport Big Brake kits generally fit 2WD vehicles only, unless otherwise specified.
