IMO, a spoler is not as effective as a well designed wing.....but a hell of a lot cheaper.
In SCCA Autocross, most classes are limited to a 10 inch high spoiler and everybody runs the max height....but the top speeds are limited to 75ish mph. My old AX car had a max height spoiler but there is no windshield or rear window.....better air flow to the spoiler. Dunno if I'd go that high for a track car unless I had HP to burn (and a windshield & all)....but it is easier to cut one down than raise the height. May not be pretty enough for a track car.

QUOTE(J P Stein @ May 10 2011, 11:44 AM)  IMO, a spoiler is not as effective as a well designed wing (IMG:style_emoticons/default/agree.gif) A well designed wing will have less drag and be easier to tune than a spoiler. That airdam will definitely increase high speed grip at the front end, so something that adds downforce (or at least eliminates lift) at the back is advisable. The more HP you have, the more downforce at the rear wheels you can use. I don't think you'll be going as fast in any of the turns at Road Atlanta as the kink at CMP, although a bit of downforce will make you feel more comfortable at both ends of the front straight. |

Anybody with "well designed" wing drawings or pics would be appreciated. I am in that black hole of mods to go faster ! Front spoiler now means brake ducts and on and on and on .......Trying to do it without trashing the car.

I installed a G-stream wing http://www.g-stream.com because I could build my own mounts and install the wing where I wanted it. Most other wings have pre- determined attachment points and must be attached at those points. It has a built in wicker, is very light and a very strong. It also has a very good down force to drag factor. The adjusters make it easy to adjust and fine tune. This wing has is made by Paul Brown (Tiger Racing) that does a lot of race prep for World Challenge Mustangs.  |
