The S550 Shelby Mustang features a lot of bang for the buck, but falls short on finishing components, one being the fender liner. Ford left a gaping hole in the underbody by not filling in this void. This void induces high pressure air into the underbody which would be better evacuated out of the wheel well, and thus our product was born.

Through CFD testing and on track testing, we found the units improve fender evacuation and as a result, increase downforce and decrease drag on and off track. We were able to reduce the coefficient of drag by 0.023 when combined with our Ventus 1 kit. This is a large reduction in drag for a street car!

These units are produced from abs plastic, which means OE level appearance and longevity. The products also fit and bolt on like a factory style part with minimal hand tools.

Note: Brackets must be modified if running full length jacking rails. Will also work with regular S550 chassis with slight modification.
