I took the advice from the guys at Jerry Woods and ran mine much higher than before. I was told to start at around 30 and work my way down if i didn't like the result.
This weekend, i had them set to 28lbs in the front and 30lbs in the rear. The compound on my 9" GoodYear's is the R250, which i believe is the softest for the 7x15 rims ...
The car felt great with those pressures, i gained about 1lbs front/rear each 2 runs and Trekkor took the tire temps in the front (the rear was clearly overworked with all that smoke i was letting out) and the temp was even across the whole tire within 5 degrees!
Another thing JWE confirmed is that you have to go easy on the negative camber. Anywhere between 0 and -1, depending on your car.
I ran -1 all around and from the tire wear, it looks like i might have to back off a bit, i think i'll go back to -0.5, especially with the higher pressures that reduce tire-roll ...
Just my observations, of course. Your milage may vary!

PS: It was good seeing someone else drive my car. Gives you a whole new perspective on what the car does in certain situations and what it is capable of.
PPS: I still can't believe those tires lasted as long as they did! I bought those from Bill P. years ago used(!) and put quite a few heatcycles on them since. The tire softener really worked and they had plenty of grippage. Well, until Brad and i started to let the smoke out of them. All 4 were down to the cords by then end of sunday, the left rear being the worst.
PPPS: I need a limited slip! Anybody got a Guard LSD for sale?
