I'm attending a PCA AutoX this weekend at Camarillo Airport in CA.
Outside temp should be mid 80's to low 90's. I'm running the stock 20" Pzeros.
I'm thinking cold temp should be F 32psi and R 36psi. Any input would be great!
Thanks

 

Not sure why you'd choose to go higher than the recommended normal setting (31/34 I think). With the p-zeros of the track, I went with around 27/28, but that included time for them to warm up, which I don't think you'll have.

 

I have a 991 C2S with PDCC. I've done 3 or 4 AX events with it so far. I've AX'ed my previous 997.2 C2S and my 997.2 GTS as well.

At our El Toro AX events (Orange Coast PCA region) I've run pressures of about 31/33 hot at my last couple of events. I started off at 34/37 hot. Since then I've been lowering the pressures, and each time my results have gotten better. Part of that is learning the car (it just doesn't understeer like the 997's) by I think the tire pressures do play a role. I also have the 20" PZeros.

Using the pressures you suggested, or even those from a previous response, your hot pressures will be too high and the tires will get pretty slippery. You could start out at 32/24 cold, or thereabouts, but you'll want keep the hot pressures from getting above that.
