If you want truly competitive R compounds, you probably need to be willing to take a hit on the speed crack pipe that is Hoosiers, and expect to use 2-3 sets per season, and by the way, the Autocross compound is not trackable.
Kumhos are good, but not that good, but are trackable. Still, depending on your driving, you may go through more than a single set in a season.
And with the Azenis sports, and similar "street tires" introduction, the margin is even smaller. With some very competitive drivers in the Street Tire class this year, we may see how good our factors really are. I wouldn't be surprised to see some "N"s near the top of the PAX list, possibly even giving the Karts a run for their money.
Take a look at the last events of the season last year... Some very highly placed Ns, and STs...
I'm going to STs
