I'm getting ready to buy some track tires. I used NT-01's on the 987S and was impressed with the overall package, especially longevity.

The car has GT2 wheels on back now with 315's and there are no fitment issues. Not sure if the PO fitted fender liners but when I look there are no rubbing issues and the camber appears to be bone stock street setting.

I got a set of stock hollow spoke twist to use for the track and will be retaining 4WD (for now...).

I've looked at some posts on the correct sizing to purchase using the 11" rear wheel and 4WD. It appears that

235/40/18
315/30/18

is the right choice?

Yes correct for 18s

"02996ttx50

sounds a little wide for a 10 wheel. certainly correct for a stock gt2 wheel. never heard of a 10 in wheel maybe a snow/winter setup..

My bad - stock 11" hollow twist.

"02996ttx50

i ran 315/30 ps2's on stock twists but had fenders rolled. not sure about nittos fitment in 315/30. i would imagine? the gt2 12" you have would be better suited to the track but would understand if you didn't want them track rashed.

Thanks all. I bought tires and we shall see how the rear fits. I've got a variety of spacers and will be lowering the car for the track duty.
