Ideal cold and warm PSI for Cup2's at the track
What should I shoot for in terms of cold and warm PSI on my Cup 2's at the track? I'll be at Laguna Seca on the 28th for my first track outing in the M2C.

I ran mine between 34-36 hot. Don't let them go over 37/38 hot, they will melt like chocolate in the sun !

Depends on ambient temps. I would suggest 28psi cold, 35psi hot.

I ran mine 32 - 34. Anything more and they would get greasy. Outside wear wasn't too much of an issue for me as I ran 3.2 negative camber

Nice Bill. We were just bustin your balls about that pricey front plate but here you are tracking at Laguna Seca. I haven't been to that track but it's on my bucket list. I have done Autospeedway and Chuckwalla and had a blast with my comp!

28psi (1.8bar) cold
30psi (2.1bar) warm start with 28psi cold and reduce to 30psi warm after a few warm up laps, 30psi warm front and rear works well at road and track for me on the cup2*! steering response is much better and the car „sits“ stable on the back/rear. I run 550hp/750nm. |
