Nothing is "passive" anymore. Everything is computer controlled and must be tied into the appropriate circuits in the correct ways. Take a look at all the CEL threads companying minor changes in C7s. Anyone think it any less likely the case with C8s?

Curious why you think you need this extra cooling? I know you’re in Texas, I’m in sc. we’re not cooking yet but I’ve been in enough stop and go traffic in 90 degree weather that I’m not concerned. I’m thinking after the c7 overheating issues gm over engineered the cooling systems in the 8.

And that's why you would have never ordered the car without Z51 in the first place. If the OP is going to track the car, he should sell this one and get a Z51 car, if he isn't going to track it, there really isn't any reason for additional cooling (unless he's going to pull a 5th wheel trailer 
).

Met want to track it a little and if it cools the engine better that would not be a bad thing . Would have bought the 51 package but wanted all season tires and was not fan of the little wing in the back .

From the presentation a pair of Corvette team "thermal engineers" did at Carlisle in 2019, it seemed the extra radiator was more for the E-LSD than the DCT itself, although it obviously affects both. If by "track it a little bit" you mean an occasional HPDE, I don't think you need to worry. The temps you're going to see doing half a dozen quick laps at a time are nothing like you'd encounter doing lap after lap at race speeds. I've done FAST laps at VIR and the coolant and oil temps barely moved above normal, admittedly on a relatively cool day (mid 70s).
If by "track it a little bit" you mean entering actual races, then what Phil1098 said. Sell it for a profit and buy a Z51.
