Description

This rear kit features a robust 4-piston caliper, meticulously crafted from a single billet of aircraft-grade aluminum. This construction ensures exceptional strength, light weight, and resistance to corrosion, while the aluminum pistons further enhance heat management for consistent braking power. At the core of this kit are the 330mm two-piece slotted rotors. The included SC5 NAOC Ceramic street pads are optimized for street and light track use, offering a 50% reduction in brake dust compared to race pads, along with quieter operation and less rotor wear. Their optimal operating temperature range is between 194°F - 1022°F. Furthermore, the kit incorporates D.O.T. compliant stainless-steel braided brake lines. These lines eliminate the expansion commonly associated with rubber lines under pressure, leading to a firmer pedal feel and a more responsive braking experience. Ksport Big Brake kits are built to order, requiring an estimated 4-6 weeks for production and delivery. This specific kit is compatible with Mazda Millenia models from 1995 to 2003 and is noted to fit 2WD vehicles only. It's highly recommended to confirm fitment with your specific vehicle before ordering. If our sales team recommends an incompatible setup, Ksport will work with you to rectify the situation, potentially waiving restocking or return shipping fees if the item is in like-new condition.
