Description

The Ksport Supercomp 8 Piston Big Brake Kit is designed as an extreme, direct bolt-on upgrade for the Lexus RX330 models from 2003 to 2009, providing the highest level of stopping power without requiring modifications. This kit features a one-piece forged caliper construction from aerospace-quality aluminum, ensuring lightweight strength and corrosion resistance. The calipers house aluminum pistons for superior heat tolerance. Carbon steel caliper brackets, CNC machined for precision, are included to allow for a direct installation onto the vehicle's OEM caliper bracket location. The system utilizes two-piece floating rotors, which allow for slight outward movement, improving self-centering within the caliper, reducing brake drag, and enhancing overall braking performance. Included with the kit are D.O.T. compliant stainless-steel braided brake lines, which prevent expansion under pressure for quicker pedal response and a firmer pedal feel. The kit comes standard with SC5 Street Pads, offering optimal braking for street and occasional track use, with reduced dust, noise, and rotor wear. Rotors are available in either slotted or cross-drilled options, with slotted recommended for track use and cross-drilled for daily driving. Standard kit components include two forged monoblock aluminum calipers, two lightweight two-piece rotors (slotted or drilled), one set of SC5 Street Brake Pads, two stainless steel brake lines, and all necessary mounting hardware and an owner's manual. Please note that Ksport Big Brake kits are built to order, and production and delivery typically require 4-6 weeks.
