Jason and Mr. Benz.
I'm still a proponent for street tires.
who cares if you "raw time" dropped... what if you practiced on street tires.. got really good, then went to r-comps.. your times would have dropped more!!!
as long as you're having fun, that is all that matters.. frankly.
IMHO... spending my own money is not fun.
so I'd rather try to be fast on cheaper street-tires... than to to be slightly faster on more $$$ tires... and have to piss with swapping wheels/tires at the event. had to do it once in the rain.. back and forth ... once...
what size wheel are you using??
just come to STU. I'll let you take my car for a spin on the AST's (which are made for M3's as well) they are so smooth, yet stick so much better than any other damper I've tried (that wasn't 3 times the price, ala Moton)
when you are ready for better dampers.. you'll already be looking forward to the AST's.
Vorshlag makes a nice 17x9 wheel that is forged and lightweight.
245/40 tires (maybe wider in the rear, if you want..) and you'll be happy!! and can still DD the car.
