The kind of tire Also makes a big Difference. Seems everyone running the star spec z1 ate having great success. My friend cut a 1.9 60' on then with his srt4. So I'd get a set in what [MENTION=185]aLmk[/MENTION] suggested. I'm running 235/45/17 on stockrims But they are fuzion zri and they spun bad at 330whp. Now even more so. My next set will be the star specs as well.
