Not a whole lot actually. The wing I had was rated for similar downforce and drag (slightly less drag and slightly less downforce), and cost me only 1-2 mph at most tracks peak speed. You come out of the corner faster coming on the straight typically because of the extra grip, and that amount of drag is not very much. A wing like that is good for 2 seconds a lap at VIR once you get used to it.
A E36 LTW wing, on the other hand, is an anchor.
