Not sure if this will help anyone but here's my current plan.
Disclaimer:
My NSX sees about 25% track time with the balance of the 75% - driving to/from the track, driving 200 miles every other wknd which can sometimes be a grueling commute, driving the car as primarily a GT car up the coast and thru canyons on wknd. It's really a MIXED-USE sportscar. It saw a decent amount of wet/damp/cool conditions this year so I need a tire that can handle 45-50 degs and not be too skittish. I don't need it to be amazing in poor conditions, which I feel my current Continental DW excels well at, but it lacks the outright dry grip of a Z2 or equivalent. I don't care about tread life to be honest but I care about grip, comfort, and noise suppression. Again, I think Cup 2s would have been my ideal tire and just so happens to also have excellent treadlife among it's peers.. In terms of track performance, I don't need all out speed at the track. Just something fun, confidence inspiring, consistent, and predictable.
Plan A:
With that said, I currently have 2 sets of 17/18 wheels in optimal NSX sizing. I will continue to keep my DOT R-Comp tires for the 25% track which will go on one set of wheels. The other set of wheels I had planned on picking up Z2s or AD08Rs for and sell the DWs.
Plan B:
I am now looking at purchasing a lightweight 18/19 to consider the PSS but i'm still on the fence between the 18/19 PSS or the 17/18 Z2/AD08r. The only reason i'd consider 18/19 is strictly due to tire choices. I don't like the bigger look. I don't like the extra height. I don't like the skinnier sidewall. However, if the PSS is my only choice here... not to mention the front tires seem slightly elusive, I don't see this choice as being worth it.
I would love to get to a point where swapping between track tires vs. street tires wasn't necessary. For my usages, the Michelin Cup 2's would have been perfect for street/track with some sacrifice for wet conditions. I'd be fine with that. For now it seems no matter which choice I go with, I'm stuck with 2 sets or "live with" a set of Z2s, which are loud, not that comfortable, but seems to be ok in wet, and sticky enough for track use but apparently not as sticky as Cup 2s (is this true btw?)
