I was driving my TT (came with N/A rims when I bought it) on BF Goodrich T/As. I could regularly break the rear loose at will and would have to be careful on wet roads. Thank the Big Guy that the 300Z handles so well. I just upgraded to 18" wheels with Bridgestone pole position tires. The difference is night and day. I recommend them but they do cost and are hard to get in some sizes due to the demand.
