First track day with the GRC with 1,300 miles driving into Sonoma!

It's a stable and "safe" car that can be made to slide or rotate with specific inputs, but it doesn't want to do it. On a low grip surface, it'd be a lot of fun but on an ideal grip surface I find I'm mainly managing understeer.

On numerous corners throughout the day my friends with GRCs and I would get power steering cuts when managing abrupt transitions (such as catching a car in a slide) - a clunk and the steering goes heavy.

My car is a premium plus with the additional radiators for coolant and the automatic transmission. Annecdontally it helps a little bit on the coolant and engine oil side (~20F cooler for coolant and 10F cooler for engine oil). This resulted in most of my sessions with a coolant temp of 180F and engine oil temp of 260F. I'm not concerned about either of those. The transmission stayed around 240F - which is a bit warm for ATF according to various articles.

Since I was in the same run group with two manual GRC's we could compare a few things, including straight line performance. Indeed the automatic, despite the bump in torque/power, is slower than the pre-facelift manual cars in a straight line. To me, this validates certain tests I've seen that show the automatic - while very capable and works great on track for either manual shifting or full auto - does not give much of an overall advantage for lap times compared to the manual cars (when driven by a good driver). 

Lastly the car is incredibly thirsty - I consumed over 1/4 of a tank per session.
