This is a subchassis for the 914 V8, it is important that the V8 motor does not move in any direction, because the shifter can end up shifting vaguely, or just braking gears when you engage half way. The air filter, and the headers have very close tolerances, this subchassis can only move one eight of an inch from side to side before some accessory will contact the chassis. We also have available, super heavy duty urethane motor mounts, and an advanced engineered cooling system. All of these things together can help you create the super car of your dreams. Any questions call Red Dawg. (661) 823-1951
