Not a bad idea, thanks for the tip! Will do some research.
Yeah, it has big, beautiful fender bulges that have some nice space available. I mean, you could of course, go with a complete aftermarket wheel setup, new tires, etc., but that's costly and the OEM parts are terrific.
FYI, there's two kinds of spacers, one that simply slips over the existing studs, for this style you need to keep it slim enough so you have a safe amount of threads for the lugs, so generally that's around 5-6mm.
The other style has its own studs, and you bolt them to the wheel hub (using the OEM studs), then use the spacer's studs to mount your wheel - these can get really wide, I ran a set of 23mm rear, 25mm front on my GT (totally transformed the stance), from a very well regarded motorsports shop. I added that last emphasis because clearly, that's introducing a serious safety consideration - people run that style on track, so it can be safe, even under extreme use case, but it's totally different vs. a slip on. I've seen people run stud type spacers from unknown sources from EBay
