In my 335i, it's a necessity due to it being twin turbo and also pushing over 400whp...
What is the normal operating temp for the Z?

Unless you want to cruise around the track in 6th gear then you need a cooler as you will be over 280 before you can finish your 3rd lap. Auto-x is okay without a cooler as you have a good 10 minute cool down period between runs.
Most people consider normal operating temperature to be 180-240F with maybe a few trips to 260F and back. Once you get above that even the best synthetic oils start to break down.
