Show original supplier description
The calipers are constructed from a single billet of aircraft-grade aluminum, ensuring lightweight strength and corrosion resistance. They feature aluminum pistons, which offer superior heat resistance and maintain uncompromised operation. This rear brake kit features 2-piston lightweight aluminum calipers for 11" and 12" systems, designed to improve pad wear and rigidity over OEM components. It includes CNC-machined carbon steel caliper brackets that facilitate direct bolt-up to the OEM caliper bracket locations, accommodating the larger caliper size. Buyers can choose between slotted or cross-drilled rotors: cross-drilled for cooler operation suitable for daily drivers, and slotted for vehicles seeing more track time. The kit comes standard with SC5 Street Pads, formulated for optimal braking performance on the street and during occasional track use. These pads significantly reduce brake dust (by 50% or more compared to race pads) and minimize rotor wear and noise. The optimal operating temperature range for these pads is between 194°F and 1022°F. Additionally, D.O.T. compliant stainless-steel braided brake lines are included, which prevent line expansion under pressure, leading to quicker pedal response and a firmer pedal feel compared to stock rubber lines. Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks. The kit is compatible with Mitsubishi 3000GT models from 1991 to 1999. Fitment can be confirmed via the vehicle search bar on the product page. It is important to verify fitment before ordering, as the sales team can assist with confirming compatibility and will assist with returns if a recommended setup is incompatible or if an order error occurs, provided the item is in like-new condition.
