What needs to be reconditioned on a tracked GT3 (street tires) with about 40-50 days over 2-3 years, maybe 6-9k track miles? I'm looking to buy it and continue tracking it.

I typically run the same amount and want to know what I should look for on the car and what needs to be re-conditioned.
On my past cars, I would sell the car and move onto something else.

Don't centerlocks have a maintenance at 12k, miles or so?
Any specific suspension components that need to be re torqued?
Caliper rebuild needed?

Have the car inspected by a knowledgeable independent or dealer - each car will be different. But there is a racetrack use manual that is supplied with the car that indicates the service intervals for many of the components when used often on the track.

Centerlocks definely all four hubs need replaced.

Just looked at the 2018 GT3 maintenance since I am getting close. At 6K track miles, replace all 4 center bolts, and the rear bearings. At 12K track miles, replace above again, plus the front bearings. Also heard spark plugs, potentially thr ignition packs as well.
