It this case you really want XW30 oil when not on track. I personally would go this Castrol 0W30.
You want HTHS in 3.5-4cp range (on track possibly minimum 3.6). With that HTHS you want as low as possible KV100. Hypothetically, KV100 14.2 and HTHS 3.7 are average values. KV100 13.1 and HTHS 3.7 are really good values. You see where I am getting to?

Okay so lower KV100 is better?
What do you think about HTHS 3.4 and KV100 11.7 lower temps/non track and 3.8/13.5 higher temps/some track? |
That would be ok.
