Description

The calipers are crafted from a one-piece billet of aircraft-grade aluminum, offering lightweight construction, unparalleled strength, and resistance to corrosion. Internally, they feature aluminum pistons that provide superior heat resistance and maintain optimal operation even under demanding use. This specific kit is configured for the front of your vehicle and includes a 330mm diameter, two-piece slotted rotor. The 8-piston caliper design, standard for 13" and 14" Procomp systems, greatly improves pad wear and caliper rigidity compared to OEM designs. The kit also comes with Ksport's SC5 Street Brake Pads, which offer optimal braking performance for street and occasional track use, with reduced dust and noise. Included in the standard kit are 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 required mounting components and hardware, along with an owner's manual. This brake kit is specifically designed for the BMW M3 E30 models from 1982 to 1992. Please note that Ksport Big Brake kits are built to order, and production and delivery typically require 4-6 weeks. The product is also subject to California Proposition 65 warning regarding Cancer and Reproductive Harm.
