Sounds pretty tight, but the low profiles help. I was running a 3/4" rear sway bar as well, but the taller sidewalls let the tire flex enough to rub.

This wasn't a dedicated track car and I really do not like the feeling of a low profile tire on the street.

They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
