Default Forgestar offsets to run square 18x10 F14 set up on Trans Am?

Plan is to run a square 4X 18x10 Forgestar F14s (DD, road race, auto x set up) on a 2002 Trans Am. Would like to be able to run a 285/35ZR18 Hankook RS3 and maybe get up to a 315/30ZR18 Hoosier A6 all around. Is it possible to get this right with just the correct offset and no spacers?

Contact nine ball he should be able to set you up with exactly what you need. The rear will be tucked in more because the rear fenders are larger than the front but it still won't look bad. You'll probably want something around +43mm offset.

Spoke with Tony today he recommended +42mm offset all around w/ the 285 tires. Have not heard about it working with the 315/30ZR18 tires yet. That is ok if the rear is tucked in a little more just don't want things sticking out past the fenders as I don't really care for that look.

Hoosier recommends at least a 11" wide wheel for a for the R6 315/30/18. The widest tire recommend for a 18 x 10" wide wheel, by most tire manufactures for our cars is a 295/35/18 or 295/30/18.

You could run also run 18 x 11's with either 295/35/18's or 295/30/18's, and the Hoosier R6 is available in a 295/30/18 .
I'd probably go with offset in the range of +45 to +47 .
