Good point, thanks! I actually like the wheels with low off-set, but surely don't want them to rub or damage the fenders. Will have to test fit them without the tires.
So the rims from a New Edge aren't going to happen on S197? There's a guy at work selling his 18" ESR CS11. Simply gorgeous, identical to these: https://musclecardna.com/lowered-ford-mustang-new-edge-carbon-fiber-coilovers.html
I thought they were 5x114.3 too
I guess you're right about the tire availability, It's time to refresh the tires on mine but they all seem to br pretty expensive compared to the 18s, so I may just change the rims to 18"s. Do you have 18x10 all around or a staggered setup?
I think 20s are a bit too big for a track setup to be really effective. Anyway, which suspension did you go with? I am kind of in the process of choosing a lowering kit for my 2012. I have 19s
