CUP-DIFFUSER The Cup-Diffuser gives a motorsport look to the rear, combined with aerodynamic styling. It can be fitted directly under the original bumper. It is hand made from glass reinforced plastic (grp) and comes in white ready for painting.

To protect the diffuser from exhaust heat use the Bonrath Racetape - aluminized glas fibre layer with self-adhesive backing for easy application (as shown below).
