What Will Our Mounts Do For You? Our rubber-to-metal bonded products are designed specifically for high performance applications where a direct replacement for the standard mount is required along with a much higher level of engine control to cope with higher engine outputs and higher road inputs caused by fast driving. The competition mounts also eliminate clearance problems with strut braces and exhaust systems, body panels etc. Competition mounts are not recommended for road use. This is a direct replacement for the original part and will reduce movement at the gearbox end of the power unit in all directions.Helping to reduce tramp under hard accelaration.
