Hi Looking for a set of American racing AR 505 torque thrust II rims 16x8 to fit 86 Iroc w/rear drum. Is there any problem fitting because the original rims have an offset between front and rear. Any one know the reason for the 1" differance. thanks.

im looking for the same rims.

Same here

I think the american racing website has the right offset posted on their website. I can say the tire makes a big difference. Personally I have 17x9 all the way around regular tires look great, BFG dragradials stick out just a bit (but not hill jack to much). Amercan Racing says 4.75" and 4"backspacing
