Im lookin at the ATS comp light wheel...17 by 7.5, i have 2 options for the offset...20 and 40....what offset should i get...id like to be about flush or stickin out just a little. I didnt see 7.5 listed in the wheel offset post at the top. If i get 20 the fronts will stick out right? http://www.discounttiredirect.com/direct/findWheelSizesByBrand.do?step=sizes&index=5 The wheels are at that address if you wanna see them. Thanks.

I can tell you that i have the BSA 259s on my xB and they are 17x7.5 with a 40 MM offset. The front i had to run with a 3MM spacer to clear the capilers, and they sit out to the fender well really nice. The rear, thats another story. I think im gonna have to go with a spacer ( like 10 - 15MM ) to get the rears out to where the front are. Only i have noticed, but its starting to bug me that the front wheels sit further out then the rear.

I'd run the ET40 front, and ET20 rear. It'll look killer. You may need to have the rear fenders rolled though, but it'll be nice & flush. You may or may not need to space the front for caliper clearance depending on the spoke design. Usually ET40 on a 7.5 width will be okay.
