Is the offset of rims measured from the mounting surface for front and back?

wondering if 17x8 with zero off set will fit under stock fenders

Backspacing

I'm running 17X8 with 17/45/235 in the rear and 17X7 with 17/45/225 in the front and it JUST fits. I did have to bend the inside lip, of the top of the fender, up a little. when I hit a real hard bump, it would rub a little. I do have a lowered suspension. the back spacing on the rear rim is 5 inches, the front is 4inches. If you have more than that they won't fit with stock struts, don't get a tire wider than the rim. it's close. Just as a precaution, I grinded away a very small portion of the perch, holding the spring in, just to give me another 1/4 inch of clearance( did'nt look like it took any strength away from the perch. I guess a coil over suspension gives you a little more clearance.

your not running coilovers right?

never mind that last question
