Track day standard Boxster vs GT4 and GT3

The Bridgestone Potenza RE-71R is nominally the replacement for the RE-11 and has a 200TW rating, so technically its Extreme summer rather than R compound like NT01. That said many feel it is as fast as Michelin Pilot Sport Cup 2 on the GT4 (and cheaper). On my Cayman R I thought that they were similar grip to the NT01 and wore out about as fast- 5 to 6 track days or 20-25 heat cycles. If you go through a lot of tires they may be worth a try to see what you think. For driving to/from track with a chance of rain, the RE-71 when newish has more pronounced tread than an NT01 so for some that may be a consideration too. Or you could just go to Hoosier R-7. Many DE champs swear by them:hilarious:
