Description

This innovative system features a unique Dual Caliper setup, utilizing a single 4-pot caliper where two pistons operate the primary foot brake and the other two function independently for the handbrake. This provides enhanced control and stopping power. The kit is a complete, bolt-on solution, ensuring straightforward installation with all necessary components included: calipers, floating brake discs, brake pads, handbrake, and all required hardware. The calipers are CNC machined with Carbon Steel caliper brackets for a direct fitment to OEM locations. For customization, Ksport offers options for Slotted or Cross Drilled rotors, with Cross Drilled recommended for daily drivers due to cooler operation and Slotted for track use. The handbrake features a polished Titanium cylinder and lever for improved feel and aesthetics. Standard SC5 Street Pads are included, offering optimal braking performance for street and occasional track use with reduced dust and noise. Additionally, all Ksport Big Brake kits come standard with D.O.T. compliant stainless-steel braided brake lines. These lines prevent expansion under pressure, resulting in a quicker pedal response and a firmer pedal feel compared to stock rubber lines. The calipers are available in standard colors like Orange, Red, Black, and Yellow, with options for premium high-polish finishes and over 20,000 custom color choices. This specific kit is built to order, with production and delivery times typically ranging from 4-6 weeks. It is explicitly listed as compatible with the 1986-1991 Mazda RX-7 Base models. Fitment for other vehicles can be confirmed via the search bar on the retailer's website.
