Looking for some suggestions on tires and brake pad wear and upgrades for the 2013 Shelby GT500. Have lots of experience road racing cars and motorcycles, but nothing near as heavy or with as much HP as my soon to arrive GT500. Anyone already track their new Shelby and replaced brake pads or tires? How long did the stock tires and brake pads last? What did you replace them with? Do you have a separate set of wheels and tires for track use? Thanks for any suggestions or insight.
