993 c2 fender vs turbo fender
 

Does anyone know if there is a difference between the 993 c2 fender and the turbo fender?

Yes. The C2 is less flared than the turbo. IIRC the turbo rear end is 2.5 inches wider than the C2.

no worries, so the 993 c2s and the c4s share the same front fender as the turbo? I am assuming so. thanks

The front bumper covers are the same size on C2 or "s" or turbo, only the rear is physically a different size. I have a Euro turbo front on my C2 cab. I am not positive that the quarter panels (wheel flares) are exactly the same.

The Turbo and C4S have more of a flare where the front fender meets the rocker panel. If you look closely on the turbo/C4S the rockers flare out more than a standard C2 or C4. So you can't use standard 993 front fenders on 993 Turbo's or C4S's. The rear quarters are also wider than a standard 993.

I looked into this last year. Apparently the front fenders are the same on NB and WB cars. However, there is an additional part/flare that needs to be added to the fender for a WB at the bottom where it meets the rocker panel.
