Looks killer! But, I would say that's your problem. The spacer is pushing the wheel too far out and creating your rub issue. I'm not sure just how much clearance you need, and if this would give you enough or not, but if you want to keep those wheels, I would look into getting the fenders rolled. I had to do that on my truck to accommodate the big wide rear wheels. Since you're only running a 255 tire, that means your backspacing is totally wrong (plus the fact that you have the spacer in there just makes it even worse), because I've seen much wider tires go on these cars without an issue. So take a look at rolling the fenders, but have somebody do it who knows what they're doing, as you don't want to hurt the paint at all.
