Description

The Ksport Slimline Big Brake Kit addresses the common challenge of fitting aftermarket big brake systems onto vehicles with aggressive wheel fitments or limited caliper clearance. Traditional large multi-piston calipers often interfere with the wheel's inner barrel due to tight spacing. Ksport's innovative Slimline Caliper design addresses this by adopting a profile similar to OEM single-piston calipers, thereby ensuring compatibility with most factory wheels or aftermarket wheels that have minimal space between the caliper and the wheel. This specific kit, part number BKMZ170-322SO, includes 304mm diameter rotors and is equipped with a 3-piston caliper configuration. Ksport USA generally designates its products for "Race Only" use, unless explicitly stated otherwise, meaning they are intended for competition and off-road use sanctioned by recognized racing organizations. Buyers should be aware of this designation. This big brake kit is specifically designed for the Mazda MX-6 from the 1988 to 1992 model years.
