I had a few people ask me for specs on the wheels that I have on my car, but I wasn't sure about the offset.... So for anyone who is looking for a set of wheels that fit as perfect as I can see, they are 20x8.5" w/40 offset front and rear. The tires are 275-30-20's in the rear, and 255-35-20's in the front. The rims/tires in the rear just barely fit between the inner fenderwell and the outer fender lip, they clear all the way from above factory ride height, all the way down to fully dropped. The same goes for the front, with the inside of the tire being about 1/4" away from the top of the spindle, and the outside just barely mising the outer fender lip, when the car is riding VERY low. The front wheels will also turn from end to end without hitting any part af the vehicle. Even with the car lowered all the way down (pretty much only for shows or pictures) I can still turn the steering wheel 1.5 rotations either way before the outside of the tire starts to rub on the fender lip! I figured I'd post this for anyone who has asked me or was wondering about fitment on a set of DUBS for their Mark VIII..... Hope this helps!
