Traction and lack of good street tires avaiable is a significant issue. My kingdom for a 275/35 15 Rival or RS3! But even with the tiny 225s it is a heck of a lot of fun to trying to bet the 0-60 time!
It can be scary if you are not careful. Bang 4th gear at 95 at the bottom of an entrance ramp and it will usually break them loose.
