Description

The Ksport Procomp Big Brake Kit is engineered as a sophisticated, direct bolt-on upgrade to significantly enhance your vehicle's braking power, especially under sustained high-heat conditions. The kit features robust 1-piece calipers, available in 6 or 8-piston configurations depending on rotor size, constructed from aircraft-grade aluminum. These calipers utilize aluminum pistons for superior heat resistance and uncompromised operation, while the opposed piston design improves pad wear and caliper rigidity compared to OEM. Customization is a key aspect, with options for both slotted and cross-drilled rotors; cross-drilled are recommended for daily drivers due to better cooling, while slotted rotors are suggested for track use. The kit also includes "SC5 Street Pads," which are NAOC Ceramic pads offering optimal braking performance for street and occasional track use, with reduced dust and noise, and operate effectively between 194°F - 1022°F. Standard features include D.O.T. compliant stainless-steel braided brake lines, which prevent line expansion under pressure, leading to quicker pedal response and a firmer pedal feel. A wide array of caliper color options are available, from standard painted colors like Orange, Red, Black, and Yellow to premium high-polish finishes and custom color matching. This specific kit is designed for the 1989-1994 Mazda 323. While Fitment Industries strives to confirm compatibility, it's always recommended to verify fitment for your exact vehicle configuration. If an issue arises due to an error on Fitment Industries' part, including situations where their sales team has recommended an incompatible setup, they will work with you to resolve the issue, potentially waiving restocking or return shipping costs if fitment was confirmed by their team and the item is in like-new condition. Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks.
