Which tire for both street and HPDE use.

I need to order new tires ASAP for my 2002 ZO6. I will be using a set of rear ZO6 wheels (10.5" X 18") for all 4 corners and need tires that will work for both street and track. I only have one set of wheels so won't be using a dedicated track tire. This is NOT a DD but only driven for fun, estimate about 2000 miles per year.
Current tires are NT05's at 275/295 sizes. They were on the car when I bought it and are heat cycled out so not much traction. I want to stick with either 275/295 or 275/305 sizes as how they look is also important (don't want to go too short on the rear for visual reasons).
From research I've done I think I've narrowed it down to the following.
NT05, 275/35 R18 front and 296/35 R18 rear. Cheaper (not the main concern for me) but reviews aren't very good in general.
NT01, 275/35 R18 front, 305/35 R18 rear. Slightly taller in the rear than the NT05's but they should fit ok. They get the best track reviews but not sure how they would work for me on the street. Cost higher but similar to the last option.
PSS, 275/35 R18 front, 296/35 R18 rear. Great tire, I had these on my 2013 Camaro and loved them on the street. I did track them a couple of times but only when cool out or wet/damp conditions. I had two sets of wheels/tires so never used them on a hot track.
I want the NT01's if I could get 4k to 5k miles and 6 to 8 track days out of them. Second choice would be the PSS if they would be usable for the hotter tracks days I'll see in Aug and Sept, high 80's to low 90's. That's the big unknown for the PSS's.
I will be running -1.5 to 1.8 deg camber front and -1.0 rear for alignment and plan on taking it easy for this season until I get comfortable with this car's abilities.

I don't have Z06 Feedback, but running the MPSS on my Cayman and 911 I would drop a pound or two to allow for the rise in PSI from the increased temps..They would probably grow 5-9PSI per tire depending on the track and the temperature. Not to mention driving style. No use in pumping them up as they'll do that on their own. MPSS is the standard by which most tires are judged. They are one of the best IMHO dual function tires and I have driven probably 10-15 diffent tires on track. Some have a bit more stick, but are less consistent or get super greasy (NT05's come to mind). You can get the Rt615K in a 315 width (I know, sounds crazy) but they are the same width as a 295 Michelin. Just another option.

Although I should clarify that I don't know where you are running and the hottest I've been on track is low 90s ambient, so, you could be in a hotter climate.

If you can at all possible buy another set of rims, I would recommend that. I tried to do exactly what you are trying to do and I found out that my Street/Track Tires heat cycled so many times by driving on the street, they were practically useless at the track. You can pick up an extra set of wheels for not too much money. Just a suggestion.

Why is there so much talk all of a sudden about tires heat cycling out via street use? I thought that wasn't possible with normal driving, the tires don't get anywhere near hot enough. I've read that numerous times here, and suddenly in recent topics the forum has done a complete 180. Anyone have tested proof that the tires are actually heat-cycling out from daily use?

Consider the Falken Azenis RT615+. I have almost a month on them, both as a daily driver and monthly autoX and they are great so far. They are quiet and track straight on the street and grip like crazy on the course.
I purchased them because they come in sizes for the OEM C5Z wheels.

I was very impressed with MPSS ZP on my 17 GS running
at VIR last weekend. The grip was excellent and stayed consistent. Wear also good. Nine sessions and only used about 1 /32 of tread. 26lbs cold.

Track day 2: OEM MPSS ZPs 1:25.4 to 1:25.5.
Track day 3: Hankook R-S3s 1:27.3 to 1:27.7
Track day 4: Hankook R-S3s 1:26.5 to 1:27.0
Track day 5: Hankook R-S3s 1:26.3 to 1:26.6
Track day 6: Hankook R-S3s with DSC Sport Controller 1:26.0 to 1:26.3 (need to tune shocks and get alignment, should net another second or so)
I've also since learned to not look at the indicated widths but rather the thread measured widths (tirerack is good about having this info). With that in mind, thread widths:
245/35/19 MPSS ZP: 9.6"
285/30/20 MPSS ZP: 11.2"
245/35/19 R-S3: 9.0"
285/35/20 R-S3: 10.7"
That is a fairly large difference for each size but I still think the MPSS ZPs outperform the R-S3 mounted to my car. I think if I were to run the two tires the same day back to back, the MPSS would be 2 seconds faster. Maybe 1 second if I picked out tires so that the actual widths matched. I also feel like both tires are identical in ample communication (squeal) which I like.
Now 1 video is stock MPSS with 15k miles, 1 video is R-S3s with 5k miles + DSC shock controller + better driving. Check out the speed differences in each corner and straight (play both together). Unless my car has lost power, the MPSS have better traction coming out of corners, netting faster straight speeds. I also know for a fact I am driving MUCH more aggressive into the corners.
