Cup Aerokit Gurney Lip

Recommended Posts

I'm having the Cup Aerokit (for 01 and earlier) installed. The paint shop trashed my Gurney Lip. The dealer suggests that I leave the part off. Has anyone done this? Does the Gurney lip in this application really do that much or is it just cosmetic? Any comments appreciated.

Patrick....I installed the AeroKit I on my '99 996 C4. The Gurney flap on the lower rear wing is, of course, a prescribed part by the factory. I kept mine out the hands of the paint shop and glued it on with the factory adhesive myself, leaving it black (the car is AS). PAG won't tell you how important it is, just that they will highly recommend that you install the kit just like they designed it. I'm no aerodynamicist, but, I do know that a Gurney flap (or wickerbill in roundie round lingo) can have a big and important effect on the downforce a wing will create. You may have seen CART guys changing very similar looking GFlaps for different car balance and drag. I don't know if the AeroKit GFlap makes a discernable difference at high speed, but, I'd buy a new one and put it on. IMO it looks good, too, to have it in contrasting, unpainted, black.....(don't tell Loren I said that '-) )

Actually the Mk I GT3 came with this lip unpainted, as was the plastic splitter under the front bumper. It's one detail that you can usually spot to tell a real GT3 from the posers who install an aerokit and put a GT3 logo on the back.
