UPDATE: Pulled the rears down to about 36 psi and the issue seems to be resolved! I may have noticed it one time quickly, but other than that did the same route and hard driving and coasting through corners and back to normal. Glad to save my brakes from unnecessary use. Thanks for the tips.

Also how do you guys feel about 33 front and 36 psi rear (cold ish)? I wanted it 33/38 as I think Porsche recommends a 5psi difference (?) but I took a bit more out of the rears than anticipated.

That's fine.

What are the ambient air temps? If I recall, you are in Canada?? If so, you need winter tires. Be safe.

Ambient temps are pretty high actually (not Canada). If it’s in the mid 70’s when I get in the car and drive up the block, it’ll be around 33/36, and then if it’s around 70-80’s out it’ll go to about 37-39 or 40 as I drive. That’s a good level for these cars?

I run 29/32 cold in N California. It rarely gets too cold here, or at least I’m not driving. Perfect.

K-A keep your rear tires below 40 hot. So if you're starting out at 36 cold and they are getting to 40-41 hot, bleed off 1/2 pound. Rinse & repeat.

Thanks. Gotta admit I was shocked at how much of a difference adding some PSI made awhile back when I was around the low 30’s cold. The car felt a lot stiffer and more sprightly. But then when the dealer added more shortly after, it got too hard and lost that just right balance.
