Hi Ed,
you couldnt say a truer word.
I wanted to restrict as much air as possible going under the car and by plumbing up the ducts to the brakes/cooler, fitting the cooler in the centre and moreso the under lip rubber, the car is much better planted than with the standard front end. The benefit in weight reduction is fantastic and the wind noise has greatly reduced.
I made my under lip from the original lower impact bumper rubber as it is stiff enough to stay rigid under frontal pressure.
Does the car handle better than standard???? 100% better - can see the results of the original development from RUF should have been adopted by Porsche.
Here is mine before the rear arch and flag (air brake) mirror replacement with RUF's.
Regards
Jammo.
