    I believe most run at least a 5mm spacer on the front to clear the caliper, or you can remove the anti-rattle clips.

    Tire size would generally be 215/40 all the way around with no problems.
    Or step it up to 235/40 and deal with occasional rubbing in the front under full lock.

      i am running the same setup with a 215 tire in front and a 235 tire in the back with a 5mm spacer up front and a 15mm spacer out back and love the look..

        Also, you'll need hub-centric rings to adapt the hub diameter.

          If you opt for custom spacers, you can have them made 72 to 74.1mm and not have to worry about those little rings. I recommend 7-10mm and longer lug bolts should be used as well.

            Custom spacers (one-piece hub & spacer) can't be fabricated unless the spacer is 10 mm thick or more. I've done the CAD and the FEA to prove it.

                I have some in 7mm, machined by a guy on R3vlimited. It is completely hubcentric and fits like a glove.

                  I'm using a 57mm stud conversion and works like a charm and fits behind the RC090 center caps as well..

                    Fit isn't the issue. Strength is however. Don't be surprised if the hub-centric ring area snaps off the spacer.....

                    That being said, I agree, it probably won't kill you or cause the wheel to de-center but it's no way to design/fabricate parts. That is all.
