Overview

It features larger calipers, rotors, and brake pads than the Procomp kit, with increased pistons and standard full-floating rotors for superior self-centering. The calipers are constructed from a one-piece billet of aircraft-grade aluminum for strength and corrosion resistance, and include aluminum pistons for improved heat tolerance.
Show original supplier description
This kit builds upon the proven performance of Ksport's Procomp series by incorporating larger calipers, rotors, and brake pads, along with an increased piston count. A key feature is the standard full-floating rotor design, which enhances self-centering within the caliper for reduced drag and more consistent braking performance. The calipers themselves are a testament to Ksport's engineering, crafted from a single billet of aerospace-quality aluminum. This one-piece construction ensures exceptional strength, lightweight characteristics, and resistance to corrosion, while the integrated aluminum pistons offer superior heat management. This kit utilizes a floating two-piece rotor design, where the outer rotor section can adjust slightly, improving self-centering and leading to more even pad application and reduced brake drag. For customization, Ksport offers a wide array of caliper colors, from standard options like Orange, Red, Black, and Yellow to premium finishes such as Silver, Gold, Titanium, and various anodized colors, with over 20,000 custom color finishes available. The kit includes SC5 Street Pads, formulated with NAOC Ceramic for optimal performance in street and occasional track conditions, offering a 50% reduction in brake dust compared to race pads, along with reduced noise and rotor wear, operating optimally between 194°F - 1022°F. Additionally, D.O.T compliant stainless-steel braided brake lines are standard, providing a firmer pedal feel and quicker pedal response by preventing expansion under pressure. Customers can choose between slotted or cross-drilled rotors. Cross-drilled rotors are recommended for daily driven vehicles due to their superior cooling, while slotted rotors are advised for track-focused applications. Please note that Ksport Big Brake kits are built to order, and production and delivery typically require 4-6 weeks. This specific kit is designed for the 1982-1992 BMW M3, with specific fitment listed for 1988 and 1991 Base models, and Fitment Industries indicates it fits a wide range of M3 models within that era, encouraging users to verify fitment for their specific vehicle via the search bar.
