Description

The Ksport Supercomp Big Brake Kit is engineered to deliver superior stopping power for your 1999-2002 Nissan Skyline R34. The calipers are constructed from a single piece of aircraft-grade billet aluminum, ensuring exceptional strength, light weight, and resistance to corrosion. They feature an opposed-piston design that enhances pad grip and caliper rigidity compared to stock, incorporating aluminum pistons for improved heat resistance and reduced weight, along with high-temperature seals for sustained performance. This kit utilizes a 2-piece disc assembly with an aluminum center to decrease rotating mass, leading to quicker braking response and shorter stopping distances. The unique slot design on the rotors helps dissipate heat, gas, and pad debris more effectively than conventional designs, while also reducing braking noise. Ksport offers both slotted rotors, recommended for track use due to their heat and debris expulsion capabilities, and cross-drilled rotors, which run cooler and provide increased bite, making them ideal for daily driven vehicles. The kit includes replacement calipers, rotors, pads, stainless-steel brake lines, and all necessary hardware for a bolt-on installation without requiring modifications. The Supercomp Big Brake Kit comes standard with a 12-month manufacturer warranty covering defects. The kit includes Super 8 Pot Calipers and comes in various rotor sizes (Front 380mm, 400mm, 421mm and Rear 400mm Systems) with standard colors like Orange, Red, Yellow, and Black, plus over 20,000 custom color options. Note that oversized items may be excluded from free shipping.
