Cup 2 track day tire life or another tire for Hpde?

Interesting that you thought the Supercar had better grip than the RS4. Quite a few 1LE guys are using the RS4 in a square 305 setup and reporting quicker times. I for one will be sticking with the Supercars because I like the way they feel, both on track and in autocross.

If you just look at various people's lap times you could assume that. Really, you need to look at someone who has changed just basically tires and seen a significant drop in time at the same track. With that, because the RS4 has good endurance and durability, you will see a lot of competitive people (i.e. Time Trials) jump to 19's and just run them or the RE71R (remember, a lot of people assume "aftermarket" tires are always better than OE anyway) - you can't use that as a data point for the tire though unless that driver has been to the same track and on the Goodyears. I've heard and seen the RE71R's put down notably faster laps than the OE SC3, but not the RS4. In fact, I've read and/or talked to other Camaro SS 1LE guys trying out a variety of different tires and stating they don't feel the RS4 has anything over the SC3 but more longevity either.

TireRack is always a good source as a rough barometer - they just completed their 2020 Extreme Performance tire test on the RE71R, RT660, SC3 and A052... take a look at that and compare it to the tests done on the RS4 related to the RE71R...

Hey
I only track the car
I had tried 7 different compound so far.
Please take a look of the thread i made.
My best to go now is 3R. But I'm looking for fastest option not about wearing.
3-4 track events if you rotate them.

If you can fit a 18
Then i would say A052 yoko. Very fast and wear very well. (At least 7-8 days)
Nt01 is great for beginners and wear well

Last
I did a test same day with 3R vs cup2.
3R are superior.

Hope this help
Alex

Curious, where are you getting NT01s for that cheap? Everywhere I look, they are closer to $400 a tire.

I got my NT01 305/35/18's for 351 per minus 100 on 4 for @ discount tire. I run APex ET52 18x11 rims. on my performance pack 2017 mustang with ARP studs and spacers.

Amazon used to have them for 308 per tire..now 337 for 305/35/18.

Sometimes Tirerack will closeout some new tires with older date codes. I picked up my Supercar 3Rs 305/30-19 last year for $212 ea. I think they had 2017 codes. If you are competing professionally, maybe this is a problem. But for for track days, I doubt the average amateur is going to be able to tell the difference between a 12 mos old tire and a 36 mos old tire (that has been stored properly). Obviously, this is kind of "luck of the draw" as to when they have these.
