quick size ?

[jbb6811]

i have a 00 z m6 w/ stock wheels and after seeing the smoothies i would like to order them for my car. but what are the stock size and offset of mine? i would like to go up to a 17 but i want to keep them (front ansd rears)at 8 or 9.5 so i can rotate them. so what should size i order? i found 4-17x10 w/275-40zr-17 on discount tire for $1500 but what offset do i need? or should i order 17x8 rims?

9.5x17 56mm offset ZR1 chrome with 285/40/17 BFG KDWS fits perfect. Great tires, not too expensive. Any wheel of those dimensions fit 4th gens with that size tire. Dont know if 17x10 will fit, depends on offset. I paid less than that for my set-up.
