Quality 1High quality and affordable manufacturing
Our brand "Mountain" of brake disc rotors is manufactured under strict quality control by Nishioka Malleable Iron Ind., which is a manufacturer of engine parts, brake parts, and other genuine auto parts.
We promise our customers safety and peace of mind through integrated production that covers all processes from the procurement of raw materials to casting, machining, and packaging at our Japanese plant.
Quality 2World-class precision
Machining precision is an important factor in the manufacture of disc rotors. We have achieved a level of precision unparalleled in the after-market industry through the use of precision grinding equipment that is specifically for disc rotors. This high level of machining precision not only produces a pleasant braking feel but also helps to improve fuel efficiency.
Quality 3The crosshatched pattern we’ve used since our founding
This crosshatched pattern is produced using a machining technique that has been used since our company’s founding. It involves a slight grinding of the surface of the pad when replacing the disc rotor in order to facilitate the initial contact with the pad and immediately achieve the brake’s intended performance.
Quality 4Dedication to brake performance that extends to the materials
This superior technology is applied to the production of special disc rotors for racing that require braking within one thousandth of a second.
