I'm really not sure exactly... I measured them once a few years ago. I think it was something like +12 in front and -6 in the rear. My numbers could be off. They aren't really sold with offset sizes; you order the rim halves by width. The front fit without a spacer but it is very close to the coilover, I couldn't add any more to the inner rim half. There is plenty of room for more inner rim on the rear though.
Front -
outter rim - 1.5
inner rim - 8
Rear -
outter rim - 3
inner rim - 7
I'm ordering new outter 2" halves for the front and 9" inner halves for the rear. I had one fatigue crack on me. See the crack going through all the bolt holes. So I decided to go for maximum width since I'm ordering new parts anyway.
As a note I didn't order the current sizes. I picked up the wheels 2nd hand from a 2001 ford mustang GT2 racecar. That is why the wheel offset isn't quite ideal yet.
