Steve,I can't seem to find how much downforce it provides at what speed, but I'd have to think that any downforce is good over the rear tires. Please let me know what you guys think.
Thanks in advance,
The stock wing is rated approximately at 66 lbf @ 90MPH, and only weighing in at 6lbs., I would believe the added downforce would definitely out weigh the added weight of the stock wing.
edit: no pun intended
