Leaving drag out of the mix, Using the XP rules, is a wing more effective for getting down force than a spoiler. I've always assumed the wing is better, but have exactly 0 proof of this. The expense of a wing can go right through the roof (over 10K has been quoted).....this makes the cheep-assed spoiler look pretty good. (IMG:style_emoticons/default/biggrin.gif)
If a guy had a cross section pattern of an effective wing ( bling wings need not apply) DIY would make sense.....but is it worth the effort? Note: XP limits the total ( that would include a dual element) wing area to 8 sq. feet. |

I was talking to Mike Simanyi this weekend about the wing on his SSM BMW as it is a pretty radical looking 3D twin foil carbon fiber piece and he said that at 80mph of wind speed at the leading edge with the second foil at maximum angle of attack it makes over 500lb of down force. He said that they had to trim the wing way out because he couldn't get enough front down force to compensate for the rear wing when he changed from a regular duel plan like is on Zust's car. I didn't ask how much it cost and his car has ~400hp right now so he has the umph to push a lot of drag but it might be worth looking into.
