Auto-xers from this season have reported similar results with the RE-71R.
I believe all the winners/top finishers were on the RE-71R. If you weren't on the RE-71R, you weren't competitive...
As far as the schedule, no Buttonwillow at the end of January to start the season?

Thoughts on starting ACS vs BW?

We have reached out to a few tire manufactures and have proposed discounts or a tire contingency program. If anyone has some contacts they'd like to share please PM me and we will send our proposal out.
Dustin,let me know what you have worked out. I have plenty of my own contacts I might be able to help with, but I don't want to interfere with whatever you might already have going on.
A spec tire would be great, but forces people to buy tires they might not really need right now.

Looks like NASA PT/TT rules are up and the Rival-S and RE71R have been assigned equal points to the NT01 and a smidge under TD's

After driving on both the RE71R (albeit for 1 day) and the NT01's I can say they are on par with overall grip and lap times at Buttonwillow.
I'm curious how long they will last, the NT01's can go 5 days competitively.

I'm curious about that as well.
If the RE-71R is only good for 3 days, then I'd rather pick up NT-01s. That said, I'll be running on some uncompetitive RE-11a and on some 2 year old ZII - no budget for tires next year. I just want to drive - only got one track day this year.
As for the track schedule - i'll see you guys at Chuckwalla hopefully. I'm going to try to get a warm up track day between now and then. No ACS for me - I stopped running that track quite a while ago.

If given maybe 2 more sessions on the RE71R to dial in tire pressures and learn the tire better, I would have shaved another 1.5 seconds easily at BW13CW. The RE71R is fast and definitely feels like there is more grip than RS3s. 86CUP puts a 2pt penalty on them and that's big enough to completely throw a car into a different class (makes sense).
Overall the new tires are getting pretty quick. Are there ways to enforce weight to make sure everyone makes the weight requirement?

There is no way the re71 is as fast as the nt01.
If that's the case, I'll stick with nt01s lol. I think most of us will prefer that.
And stick with rs3s for street tires, too bad they are gone till next year.
