Carl,
08 / 09 cars are fine and have the latest and greatest swing arm oil pickup and revised pan along with a better oil pump. Do install 15w50 Mobil 1 if you plan to track your car.
I've pulled sustained 1.35 G's in my ACR at 130 mph on Hoosiers - no oiling issues whatsoever. Wouldn't try that in a 03 - 06 car without the swing arm oil pick up and pan.
As for this track, we've driven it and it's ******* tires. I recommend you avoid the temptation to go as fast as you are capable of or you will melt your PS2's.
So Cal Club plans to attend and watch the racing on Sunday this year. SRT is not sponsoring, so we won't be able to do any sedan laps as of right now.
Be careful.
Dan
