P2M solid motor mounts were made with HRC-80 hardness urethane molded material to help keeping your engine steady at high rpm and high horsepower motors. By keeping the excessive engine vibrations at the minimum can help transferring power to your rear wheels much more efficiently. Combo with our upgraded urethane transmission mount (TMK-0134-HC) will be a perfect match. The mounts were designed to be about -5mm lower than stock mounts lowering the engine more towards center of gravity for improved track performance.
