sent you a im but will post up the specs here. sawblades come in 2 sizes and 2 different types of faces or spokes. there are the machined faces which are the nice ones, and then there are the round faced ones.sizes. 17x8.5 and 17x9.5.(there is a 17x11 if you find 2 i will buy them) they both have an offset of +56mm. bolt pattern is 5x4.75in or 5x120.xx best adapter size is 33mm or 1.3in. i got my adapters from adaptitusa.com. 33mm on all four corners. they are hubcentric but not wheel-centric. it will give you a total offset of +23mm. the amount of tire stretch is up to you but you do need stretch. my front tires are 215/45-17's and the rear are 235/45-17. i still rub.
kinda hard to see but my fronts are machined faces and the rears are round(winter wheels)
