Well I thought I would get another track day out of these.
These are the fronts inside.
Only thing I can pin this on is possibly too much street driving with track camber settings.
Had one track day in Houston and then Camaro Con in Vegas. I did drive around Vegas a bit and just a couple trips across Houston but that's about it. Guess I'll need to start moving back and forth between track and street camber.
Good thing I saved the previous tires that still had a day left in them.
They were also run with track camber and wore perfectly. Don't think I ever hit the street with them.
