Okay unfortunately I cannot tell you what the offset is, but I bought new wheels and I really like them. The wheels are 8.5 x 20 front and 9.5 x 20 rear. The tires are Michelin PS2 245/35zr20 front and 285/30zr20 rear. The fronts are giving me a problem rubbing on the inside of the wheelwells, the plastic not the body. I also had to grind the stud for the link at the top down to just below the nut for the height which I wasn't happy about, but the look is awesome. So, I ordered 255/30zr20 which will increase the width just under .4 and decrease the overall diameter by .8 I believe and this should cure all the problems and still give the killer pimped look. Maybe not everyone likes it, but everyone I've shown it too likes it much better than the 18's.
