Description

This kit is a sophisticated bolt-on solution, providing the ultimate in braking capability. It is specifically designed for the rear axle and features a 356mm rotor diameter and a 4-piston caliper type, as indicated by the specs. Constructed with performance and durability in mind, the calipers are forged from a solid billet of aerospace-quality aluminum, ensuring lightweight strength and corrosion resistance. The use of aluminum pistons enhances heat resistance, while heavy-duty seals and high-temperature seals protect against extreme conditions. The opposed-piston design ensures consistent pad wear, and features like Titanium Brake Pad Retainer Clips and Stainless-Steel Brake Pad Wear Plates are standard. The two-piece design allows the outer rotor section to expand and contract independently, reducing warping. Cross-drilled rotors are recommended for daily driven vehicles as they tend to run cooler, while slotted rotors are better suited for track use due to their ability to dissipate heat, dust, and gases more effectively. Standard equipment includes SC5 Street Pads, offering optimal braking performance for street and occasional track use, with reduced dust and noise. An upgrade to RCI Race Pads is available for those seeking maximum stopping power under extreme track conditions, though these are not recommended for street use. The kit also comes with D.O.T. compliant stainless-steel braided brake lines, which prevent expansion under pressure for a quicker pedal response and firmer feel. Customization options include various caliper colors and upgrades for the center bell. This product is made to order and is non-refundable. It is compatible with 2WD vehicles.
