Only time this has happened to me is when the tire pressure was low.

hey al,
ok well that displaces our therory that only superformance has this problem. as for as air pressures. rodger kraus says to run 24 front and 22 rear. i have since noticed that the tread is thinner in the center than the edges. indicating over inflation. so i have since lowered to 23 & 21. i think it seems to help alittle but still got the wobbles

Jeff,

Then it is a Superformance problem!

I'm bumping this back up to see if I may have found the cause of my problem at least. Last year I stored my cobra on four of these wheel dollies from Summit Racing. Later the wheels were found to be "out of round" (see my post above). I am now wondering if the dollies caused the problem.

Anyone else have any experience with them?
