15k on the fronts is not terrible on these cars. But try, at the very least, a neutral setting (0.0) for the front toe...a degree or two positive is also good.At 32k miles I am on my 3rd set of front tires for my 2014 Gran Turismo S. I have had a couple of alignments one indy shop , one dealer to factory spec, but the inner fronts still seem to wear out at about 15k miles. I'm guessing that a tad less negative camber might solve this issue without affecting handling too much.
Has any one out there found alignment specs for the front that keep the car from eating front tires? If so could you please share them with me
