"Traction Limited" is a good way to say it.. that's the only reason I've left mine stock.. even here in Vegas in 115 deg full sun today, I can't find a street tire to stick in 1st or 2nd gear... anything close to half trottle and I'm fishtailing from a stop. I was thinking of going to Pirelli Trofeo R at least on the rear for traction.. I found some improvement in the Michelin 4S tires, when they were relatively new and I went to a 305/30-20 in the rear, 265/35 20 in the front. The 305s, in my opinion look a lot better for the rear on this car too.. no rubbing, perfectly fit the rim too.
