my guess is you should have researched and asked more questions on the set of winter tires/rims you purchased.I actually bought an 18" winter/tire set a month before I got my car. But we attempted to put them on Friday night and the fronts didn't fit over the brembo's. I don't understand it as the previous owners used them for 2 winters on his scat pack and I thought the 1320 had the same size brakes as the base scat pack. So right now I'm riding with the black 20" drag wheels on the front and chrome 18" wheels with winter tires on the back. I'm thinking one of those spacers with the adapters (if that is what you call it) may work as it looked to be about an inch or so to where the rim gets a little bigger. I know I should have measured it as I'm not sure if 1.25 will work or if I should try 1.5 or even 2" to be sure. I hate to have them stick out too much though. I also did a quick search for 19" wheels, but that would be pricey and it doesn't look like they make the vision 5 rims in that size anyway.
i would defiantly not stick the fronts on spacers so they fit..call tire rack order the correct setup and sell the set you have...i mean seriously it's not a clown car you bought.
