Can you tell us results of your testing of the diffuser in regard to increase top speed and increased gas mileage? Thanks
Is the diffuser compatible with aftermarket exhausts? If not all, which designs are compatible? Thank you.
you got PM.We can shorten the fins, no problem. The fins are the same height off the ground as the rest of the underside of the car. The fins also sit parallel to the ground.
