They are universal 5x100 and 5x114, I had a good hookup, I got the rims for 600 bucks. But you can get them from http://www.wheelstudio.com (I think that's the site I saw them). They are 18x7.5 and I believe the offset on these is 48. We also weighed the rim prior to putting the tires on, the rim weighed in at about 20lbs.
