PSS pressure on a bone stock M2C

Hi everyone,

I have tried going through pages and pages of threads that we have here but I was not lucky enough to find anything about track PSI recommendations for Stock PSS on a bone stock M2C

This weekend will be my first time on a track with this car and my uncle and I are going to an event at button willow. I was checking the temps and its gonna be HOT! 95 high I believe. Any starting points for cold and hot PSI settings for the car?

While I am familiar with the track, this will be my first outing in a rear wheel drive car. Not intending to go crazy but really want to get to know the car at the limit. I've probably done 20-30 laps on the same track with the C43 (AWD 4klbs) previous car that I had but know all the breaking points and racing lines I learned with that car are all out the window.

Any tips people can toss my way would be much appreciated! especially people who have ran Button Willow with an M2 or M2c!

Start with ~28 or so cold, and target 33-35PSI hot. MPSS gets greasy over 35 or when tire temps exceed 90c. Outside of that they should be pretty grippy once over 60c.
