I raced my 968s with Millers oil with the 60w viscosity it was originally recommended by Karl Poeltl a very successful 968 racer, just my personal experience.

That (oil pressure when hot) is what drove me to consistently use 20w-50. My oil change last year was done by a mechanic who was doing other work at the time (oil pan gasket replacement, as an example). He replaced it with 5w-40 and I was seeing oil pressure drop to ~18psi at hot idle, which seemed pretty low to me. Replaced with 20w-50 and haven't seen below 25psi at idle since. I'm in Texas with average summer temps in mid-90s fahrenheit and on the seldom days in winter when it's actually "cold", I just drive it very gently until it's warmed up.
Agreed. When the engine was cooking in the French highway traffic queues on the way to Le Mans the low oil pressure had me concerned - both cars. Upping the hot number really made a difference, with the 964 barley dipping below 25-30psi (although still think I'll wire in a direct high speed fan switch some point).
Well not today, but 2 days ago; did my second PCA DE Track Day at Laguna Seca.
Other than turn 11, I did the entire course in 3rd gear. Thinking about a quick/quicker shifting transmission/linkage. Instructor says that you loose one second per shift...
Track has been recently resurfaced and is super smooth.
Tightened up the two lockdown bolts for the AC compressor to complete the alternator replacement project
on my '94 Black/cashmere coupe! Test drove 10 miles...no issues so far!
What are your summer tires and what are your winter tires?
All on 17 inch rims?
