Spoiler Angle

[citiracer]

I know that changing spoiler angle will help tighten the car in slick conditions. But I'm wondering how much of a change and how big of a change it truly is (as compared to other changes you might make to tighten the car). We run our spoiler at about 60 and have never changed (just check it to make sure it's there). Would a change to 65 make a noticeable difference in the slick? Or should we even come back down a little for when the track still has some moisture? Just looking for some direction before we start playing with it. Thanks!

circle track magazine had an article a year or so ago on wind tunnel with dirt latemodels . think i remember they said any more than 65 deg. created drag and not as much downforce .
