odd on the hoosiers. must be cheater tires (if you have the right rim width) - do you think you were rolling onto your sidewall?

Don't forget spacers weight. I don't believe there is any way to increase acceleration by installing taller tires on a Boxster unless you are testing 0-60 & don't mind sacrificing a clutch. I've never seen a 275/30/18 tire.
