Re: Mk2 Swift GTi Rally Car Rebuild

From a maintenance point of view one of the worst things with any fwd rally car is the hammering that the floor pan gets from gravel coming off the front wheels. Plastic shielding in the wheel arches and down both sides of the floor helps a lot with keeping the floor in an ok state.
