My boyfriend bought me a staggered set of corvette sawblades for christmas. 17x8.5 in the front and 17x9.5 in the rear. I'm looking to put these on my '09 g6 and I'm almost positive the stock et is 50. Has anyone ran these before or something close to these? If so do you know what the et is so they sit flush or have a slight poke; Curious to know what the right size adapters would be to run. Please post pictures! Keep in mind we plan on putting an eibach pro kit or something similar to that on it probably in the summer. Thanks guys.
