Hey all! I'm brand new to the mustang family and I just picked up a 2013 GT Premium with a few things already done to it, those being a Hurst short throw shifter, 3.73 Gear ratio, Roush Cat-Back Exhaust, and then some aesthetic stuff that I'm not too worried about getting in to. My questions are as follows:

• The previous owner installed some 20x12 Forgestar tires with Michelin Pilot Sport tires, which seem too big in my opinion. I was thinking about swapping for some 19x10-11's...
