Any wheel company (CCW & Forgeline are two of my favorites) that you "should" be dealing with will have all of the wheel measurements worked out for you already. Just be sure to decide if you will be upgrading your brakes at some point in the future. You don't want to go crazy with a huge lip and then not be able to upgrade the brakes because of clearance issues. Also keep in mind that if you will lower your car or have already done so, the Michelin rear sizes in 20" will most likely rub. The INVOs will not rub.
