Show original supplier description
Each caliper is precision-machined from a single billet of aircraft-grade aluminum, ensuring exceptional strength, light weight, and corrosion resistance. The inclusion of aluminum pistons further improves heat management and operational reliability. This rear big brake kit for the Mazda Millenia (1995-2003) features lightweight 4-piston aluminum calipers, which improve pad wear and caliper rigidity compared to OEM designs. It comes equipped with two-piece rotors, offering a balance of light weight, fade-free performance, and effective grip for both track and street use. Additionally, D.O.T compliant stainless-steel braided brake lines are standard, eliminating line expansion under pressure for a quicker pedal response and a firmer pedal feel. Customization options are available for caliper colors, including standard options like Orange, Red, Black, and Yellow, as well as premium finishes such as Silver, Gold, Titanium, and Glassy/Hard Anodized Colors, with over 20,000 custom finishes possible. Rotor options include both cross-drilled and slotted designs; cross-drilled are recommended for daily drivers due to better cooling, while slotted are advised for track use. The kit includes NAOC Ceramic SC5 Street Pads, optimized for street and occasional track conditions, offering reduced dust (by 50%+) and noise. Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks. This kit is specifically designed for 2WD vehicles only, unless otherwise stated. Fitment is confirmed for the Mazda Millenia from 1995 to 2003.
