I think this is exactly how I would spec my GT4rs as well, Sb with gold wheels or black with silver wheels but no WP for sure, love the look.
Also, you were lucky and got the michelins, I see some here are getting the Dunlops like I Have and let me tell you, they are complete trash for track days as they fell apart fast, they did have good grip.
Here's what mine looked like after a couple track days, they seem to degrade very very quickly from totally fine to bad bad shape....in my 2nd to last session on one part of one tire was going and then the last session they just completely got incinerated:
Wow.....stock alignment? What pressures?
I'm going to the first track day next weekend and have the Dunlops. First time I try them at the track.
stock alignment which seemed fine as you can see it really wasn’t all wear on one side of any tire, in fact the middle patches were the first to go and I was at around 30 cold, 35 at peak temp.
my first track day everything was totally fine and I will add I got a little crazy on this last one with some drifting chris Harris style kind of thing as I do sometimes late in the day, not a ton but i was doing it sometimes. And outside temp was not hot around 55 degrees
ran a 122..9 at the streets with these wrecked tires (lots of room for improvement) and ran a 158.8 (with a 200 lb. Passenger) at Buttonwillow the previous session so they’re sticky…they just seem to fall apart
edit: 122.9

I did an alignment on mine...hoping I have better luck.
Will post results....it will be a single day but ambient temps will be more like 80F and the track surface is not the best in some areas

You need more camber man and drop the pressures to 32-33 hot by going out cold around 26-27. Cup2s don't like high pressure. My favorite track/street combo tire was the RE-71R for the 981 and 718 GT4.

I went back and forth on my last track car 4s/supersport to cup2 and the 4s just last so long and are so strong, never chunk. They just don't have near the grip of the cup2, but I am fine with that as I love the longevity.
On the pressure front which is interesting is I'll never forget when we first tracked our 997.1 gt3 in the late 2000's when I was really young and new to tracking, the front end grip of the 997 gt3 is just terrible, being this is the 718 forum, I can tell you guys, those 997 GT cars just have such atrocious front end grip that they fixed big time with the 991 and the 718 is much much better. But! there was one track rat instructor with a 997.1 GT3 as well that swore bumping the front's of the first gen cup2's to 40 psi hot was the way to go and sure enough we did that and it felt like it had more grip. This makes no sense to me today and it was a long time ago as I've had pressures too high and you just lose so much grip but on those 997 GT's it seemed to actually help so I've always thought going a tad high on psi on Porsche's can't be that bad as my worst experiences/learnings at the track is under inflating cup2's and getting sidewall wear, even with good camber
EDIT: 40 psi on the fronts only

To follow this up my buddy just tested the RE-71RS on his 718 GT4 at COTA with splendid results. It might be the go to hybrid tire.
My car went into production on 2/13 and was supposed to be completed on 2/20 but now the completion date got moved back 3 weeks to 3/13 and my delivery got pushed back to mid-April.
