Competition Engine Mounts for SR20DETDepending on supply conditions the polyurethane used for the manufacture of these engine mounts may be red or black. In both cases the difference is only visual and shore hardness is always 80 ShA. Developed in-house by DriftShop these mounts are the ultimate performance engine and transmission supports for your Nissan fitting directly in place of the original parts. The original rubber engine mounts wear out and fail over time giving many problems such as difficult gear changes knocking noises and vibrations. Much stronger than the original these DriftShop mounts are machined from forged aluminium billet and reinforced polyurethane (Shore hardness = 80). They are particularly suitable for performance use such as circuit or track with engine power increase or for engine swaps.
