Description

Designed with drifting and rally racing in mind, this kit utilizes a single 4-pot caliper, with two pots dedicated to the foot brake and two for the handbrake, each running independently on its own system. Constructed from lightweight forged one-piece calipers made from aerospace-quality aluminum, this kit eliminates weak spots and ensures consistent strength. The caliper pistons are aluminum and protected by heavy-duty seals capable of handling racetrack temperatures, while an opposed-piston design ensures even brake pad grip and wear. The two-piece design also minimizes rotor warping due to heat buildup, and the rotors are heat-treated and balanced for optimal performance. Standard equipment includes SC5 Street Pads, providing optimal braking performance for street and occasional track use with reduced dust and noise. An upgrade to RCI Race Pads is available for extreme track conditions. D.O.T. compliant stainless-steel braided brake lines are also included, preventing hose expansion under pressure for a quicker pedal response and firmer pedal feel. This kit is made to order, and the estimated delivery time will be provided after the order is submitted to the supplier. Custom caliper color options are available, including standard painted colors and premium high-polish finishes, with extensive custom color choices possible for an additional fee. Center bell customization options, such as Titanium Center Bells and Hardware, are also available.
