Wheel Offsets?

A lot is dependent on if your car is lowered and if you have the rear located solidly with a panhard bar as to which offset you can use.

In my case I have a panhard bar to control lateral movement, so I was able to go with a 15mm offset using a 9" wide wheel and a 275/40-17 tire along with being lowered 1.5" and I have never had a rubbing issue.

Up front, I used an offset of 17mm with an 8" wide wheel and a 245/45-17 tire and no rubbing there either.

Front and rear are very close to be an equal distance from the wheel well lip, I think the rear is about 1/8" in more so if you wanted to get it exact I would go with a 20mm off-set on the 8" wide wheel up front. That was my intension but I could not find a 20mm offset in the wheel I wanted.

I like those Halibrands too but couldn't find the off-set I wanted at the time either, but now there is a guy out in California that has some manufactured for a better off-set using a 8" up front and a 9.5" rear. Here's the link:
