911 Slow, have you tried the Grand Am uprights?? I put those and a crawford wing on a GS car and I loved the view out the back.
I run it fairly flat and did not notice alot of drag.

 

Thanks, probably the Grand Am was the race / class I was referring to..
So those upright were standardized by a rule? How taller are they?
Did PMNA offered those or they were outsourced?

 

Yes they were a spec item by the rules. I can measure it next week, in the interim, I would suggest contacting James @ GMG in So Cal, I think they used the same upright as the World Challange Series in 08 &09. I believe they are using a Cup S upright on the 10 & 11 cars now.

The older uprights are not available at PMNA, but I think GMG may also provide them.

 

They're made by Crawford Composites (704) 483-4175 though you could buy them from Porsche Motorsports (not PMNA). They're about 3 inches taller IIRC.

 

Thanks guys.

I found a pdf with the Rolex GT rules for 2001-2005 cup cars.

under section 2-19.8 says "All cars must use the upgraded rear deck lid wing supports as supplied by PMNA".. but gives no further details.

3 inch taller could work..
