    Just curious if anyone has continued to run the track spec'd negative camber on the street and had enough miles to determine tread wear. I have yet to go through a set of the sport cup 2's and am figuring that you would see cord on the outside before you would experience getting down to the tread wear blocks on the inside. If that is indeed the case, I'm not sure how the negative camber would hurt total tire life.

    I assume you're referring to the newer GT350. If you are then yes. I have the FP recommended track alignment for the last 2-3k street miles and the last 4 track days I've attended. For the amount of street miles vs track miles, IMO, this isn't enough camber. I'm wearing the outside of the tires more at the track than the inside on the street. Before my next track day I'm going to go with -3.5deg Fr & -2 Rr. Hope this helps.

    Same here. I have the '17 and have had 2600 miles total since new, with about 5 track days (25 heat cycles) and tread wear is predominantly on the outside of the tire despite regular rotation. I hear part of the culprit is the different rubber compounds on different part of the OEM tires, but not confirmed.

    How are you fairing with the latest camber adjustment?

    Sorry, I must have missed my notifications for this post. I also didn't realize you were talking about Cup2 tires.

    My previous comment was referring to GT350 OEM Pilot Super sport tires. Adding front camber (from -1.5deg to -3deg) didn't help corner entry speed at all for this tire. I ended up cording the inside of the front tires before the outside (I drive to the track). I'm going to try -2deg camber on my new set of front tires.

    Adding camber to the rear didn't work out all that great because the rear was a little loose on power during corner exit (I'm currently running no toe in the rear which could also be the culprit). The tire wear was a bit more even across the tread. For the rear I'm going to try ~-1.5deg and add some toe in as well.

    I hope this was helpful, here's a link to my thread that may explain a bit more

    There's a confounding issue with the Michelins for our cars: the rubber on the outside of the tread is softer than the rubber on the inside. I ran a set of Conti's this year with -1.8 degrees up front and -1.1 at the rear. Over 500 track miles the Conti's wore very evenly across the tread. I've also run Michelin PSC2's with the same settings and they definitely wear faster on the outside. Here's what the Conti's looked like at 500 miles.
