Hmmm. I've done three track days in my E93 this year (two with the roof-down) and have been taking the corners fairly hard. Other than a tiny gasket issue (that was fixed in a few minutes) I've not experienced any problems with the roof' mechanism nor alignment. Now at 22,000 miles. And I drive, daily, up and down a stupid driveway ramp that puts the frame into a hell of a twist.
I suspect that keeping the car flat on a parking lot and drifting the end around for a minute or two will do zero to the roof alignment.
I seem to remember when you got the car -- how many miles are on your tires to cause them to go bald?
