<< Jay,
I own the sidewinder (with a 42lb wing on the roof) A-Mod with arguably
the most downforce/lb in all of autocross. (at the huge expense of HP) If
anything, I was the most likely to experience this so-called problem with a
high huge wing. Believe me that the roll over that happened was due to too
narrow track and too high a CG. It has little to nothing to do with wind on
the side plates. That load is most likely in the range of 10 to 30 pounds
(20lbs wind * 48" end plate height = 960 in-lbs) by comparison to the 1500
or so lbs of cornering load(1500lbs cornering * 12"cg height = 18000
in-lbs). We were pulling higher cornering loads in the right-left setup
(1.65g) to that corner than we pulled in the upwind section of walls(1.35g).
The issue is If a car is up on two wheels caused by cornering then the side
plates could be the LAST straw that broke the camels back not the biggest
straw.
