Sources for STU sized Wing??

[Mrsideways]

Save your paper; that request has already been submitted.

I have a copy of that Pro Racing document listing the APR GTC-200 as an explicitly approved wing for WC Touring as of November 2009 (right before they changed the rules to the new classes for 2010 <rolleyes>). Given that the 2010 PRR did not include the specs from the 2009 PRR, and the 2009 PRR was referenced for the 2010 GTS class, that change was never published elsewhere.

Regardless, a little birdie told me that STU/L will probably be keeping the 8.5" chord requirement, but with the APR GTC-200 wing specifically allowed due to its prior inclusion in WCT 2009 (as I understand it, all other wings from the 2009 PRR meet the 8.5x48 requirement, which is where that dimension came from).

That, of course, is nothing more than personal opinion, rumor, and innuendo, and - of course - is not actually official/approved until it appears in Fastrack.

Sit tight.

P.S. For technical reference, a wing's "chord" is the straight-line measurement from the center of the radius of the leading edge to the center of the radius of the trailing edge. Ergo, it's not a distance that can always be accurately measured with a tape...

I searched and searched for a wing. I called APR to see if they could trim theirs. At that point they told me the website was wrong and that it was 8.5 and that they had submitted it to the SCCA and it's legal. So there it sits on the back of my car. On top of that it was one of the more reasonably priced wings. I was on the receiving end of some rather negative comments towards club racing by some of the "time Attack" wing suppliers out there. It was starting to get depressing hunting for a wing.

Not sure where you're going with that, Mr. Sideways, but I just want to make sure you read the latest Fastrack? The APR GTC-200 has been explicitly approved for use in STU/STL, regardless of its size:

Greg, No where to go with that, just seemed the WING world doesn't seem to care about club racing.
I'm excited that it's legal. I skimmed the fastrac but didn't catch that the wing had been outlined as legal. That's relaxing as I just walked out and measured the wing at 8.6ish inches with a tape measure.
Whomever I talked to at APR mentioned they had received a lot of calls regarding this. At first it seemed like he was brushing off my legal concerns but I could imagine anyone's persona after receiving the same call over and over.

Edit... just spotted it. I didn't read far enough down.
"SUPER TOURING
1. #3276 (Phil Phillips) APR Wing - SCCA spec - chord width
Add to end of sentence 9.1.4.D.2 STU and STL
“APR performance wing GTC-200 part #AS-104801, variable cord length (8.75” Inner/6.75” Outer), is permitted.”
