This top dollar for wheels for which you seemingly can't be bothered to figure out how to add pictures (or post actual offsets). You're already going to eat a big chunk of change because the fitment is so odd. I've held my tongue till now (7 months, gotta be some kind of record for me), but since this keeps cropping up and I'm actually curious...
What made you think's you could only run 8s up front? Why pay $5k for wheels in a stock width?
What were you plans for the car that made 3" of wheel stagger sound like a good idea?
Can you send them back and eat the restocking fee?
Buy conversion spacers and sell them to a 911 guy?
This sounds for all the world like you lucked into a "deal" then decided it was way to out of whack to actually use and you're trying to flip the problem onto someone else. If you actually paid the $5k, well ummm a little research before spending thousands of dollars might be a good call next time.
