Get a proper alignment first. I mean, eating through a tire that fast is unusual. Either the toe is way out of whack or something.
Pilot Super Sports are stellar tires for the track as mentioned - get some and use 'em.
After that alignment though! Get as much camber in the front as possible, that will reduce the wear.
