Ive got a 99 Z w/ bolt ons (330hp/320trq)...
What size dr's am i looking at? I was thinking 315's since thats the size tire i have for daily driving, but im having a hard time finding that wide of a rim for cheap. I do have some spare SS rims (10 spoke) 17x9 i think. Prob hold a 275... is that good enough?

 

275's will be enough..

I'm a bigger fan of the 245/50/16's tho do to more sidewall.

I used to wrinkle my nitto's on launch

 

i am sure a set of 275/40/17 DR's would be sufficient especially set at 22psi,see ya at the next meeting

 

I used to have to drop my nitto's to 14 psi or so to hook at the tracks I frequent
