Fast Road Rear Diffuser

This is a GRP rear diffuser that’s made to work with our boot floor delete. Rear cross member of the subframe must be cut out and a new box section (1inchx1inch) must be welded higher up therefore the diffuser can be moved to the point it hits the underside of the spare wheel well. A cut out is also needed on the rear valance to make space for the diffuser to sit properly. Please not this is not a show level finished rear diffuser. Its made for fast road minis to add more stability to the car when its pass over 100mph.
