Advice on tire pressures on track (Z8)

I'm taking my Z8 to the track this weekend to play a little. I know the stock runflats are very suboptimal for this purpose, but does anybody have any experience with optimal pressures for these tires? I know I will be frustrated with these tires, but I must frolick. Must.

For frolicking purposes you might try 28-29 PSI cold all the way around. You might also check them when they are hot, right as you come into the pits after hard lapping....they should read between 34-36 PSI.....Just an educated guess from a track junkie.

ask Macfly at his website at www.bmwz8.us

he tracks his Z8. I believe he says the run flats actually do quite well on the track.
