Now that I've had some wheel time, I wanted to expand on your question. While my first reply stands (no rubbing, etc) I've discovered that by having the spacers on the front wheels only (so far), this creates a playful amount of oversteer. It gives the inputs from the wheel a noticeable increase in output. Now, because of the wider front track this does mean that once you're turned-in around the 2:30-3:00 mark on the wheel, any gap in the steering linkage and/or body roll is a tad more exaggerated. I'll be adding some spacing to the rear eventually, so this will all work out in the end.
