8-Piston 330mm Slotted Big Brake Kit

The Ksport Procomp 8-Piston Big Brake Kit is a high-performance upgrade engineered to significantly enhance stopping power, particularly under sustained high-heat conditions. The kit's calipers are constructed from a single piece of aircraft-grade aluminum, providing exceptional strength, light weight, and corrosion resistance. These calipers utilize aluminum pistons, which offer superior heat management compared to standard materials, and feature an opposed-piston design that boosts caliper rigidity and improves pad wear over OEM systems. This big brake system employs 330mm two-piece slotted rotors, designed for fade-free performance and effective grip on both the track and street. The kit comes complete with Ksport's SC5 Street Brake Pads, known for their optimal braking performance in street and occasional track use, offering reduced dust and noise. Additionally, DOT-compliant stainless steel braided brake lines are included, which eliminate expansion under pressure for a quicker pedal response and a firmer pedal feel. Specifically tailored for the Lexus GS300 JZS147 models manufactured between 1993 and 1997, this kit ensures a direct fitment. The two-piece rotor design contributes to reduced rotating and unsprung weight, while the slotted rotor surface is recommended for vehicles experiencing more track use, as it effectively expels gas and pad debris and helps reduce braking noise. Ksport Big Brake kits are built to order, and customers should anticipate a production and delivery lead time of 4-6 weeks.
