I'm doing an experiment. Yes the board does have a downforce that downforce is not in effect until 120 or more. I tried to check to see if the smaller is like a drag chute holding me back and I found that in and 71° weather I ran the same times as I did and 60° weather so that's why I modified everything so that I can remove the wing at the track there'll be no problems up to about one 130,,135,, if it works my speed should increase without the rear wing I've also been looking at a way to lower the pitch on my spoiler.. other words make it almost level it would still work at high speeds but it would not be a drag at lower speeds.right now I'm doing some other mods so I'll let you know when I get back to the track and run two three runs with the wing and then 2or3 runs without it. Then install the wing back on and run two or three more to make sure that as a temp cools down,, that way we get good results .it will be at the end of February or early March before I get back to the track so I let you know what happens Jim
