The Conti DW's that are on the car now are considered a "max performance summer" tire. The car has been parked for a couple of weeks, and I took it out today after re-installing the 3rd brakelight... man, it
DOES take some miles before the parking flat spots come out!!
Thanks again for all the comments and info!!

Anything north of 30 psi will be fine... If it feels "wiggly" at that PSI, just bring it up until you've reached the right balance of comfort and feedback. Keep an eye on wear patterns, that will be the biggest indicator as to the optimal PSI. I have dropped rear PSI to as low as 18 when I was at the 1/4-mile track, to give the sidewall a bit more flex. But once you leave the track, just be sure to bring the PSI back up to a safe level.
