Hi all, Im going to track prep my '19 Z06 manual and have a few questions.

1. I understand the 2019s have DOT 4 brake fluid installed, is this satisfactory fluid for a beginner? And stock brake pads ok for novice?
2. Engine oil? 0W40 I hear is ok for street and track use? Chevy dealer put 5W30 full synthetic at 500 miles.
3. I have the harder compound Michelins, what is recommended tire pressures cold?

Thanks Brian !!!
