Tire pressures for Nitto 555RII's
Doing an HPDE tomorrow and wanted to get some input on what kind of tire pressures I should be shooting for. 
Little info on my setup: running OEM C5 Z06 wheels with 275/17 front and 305/18 rear 555RII's. Camber is -1.6f & -1r with 0 toe all around. Last time out I couldn't find the 'sweet spot', either the rear felt like it was sliding or the front felt like it was rolling over.
I did some searching last night and found only one thread where someone contacted Nitto and they suggested 36f/34r HOT. More input would be appreicated.

That's about right ... I've run the same tires and essentially the same suspension settings.
I start out at 32/30 and look to come off at 38/36 hot - depending on ambient/track temp, I may have to bleed off a bit after second session. 36/34 might help the center wear, as I wear the centers more.

I just wore out a set of the 305/18s in the middle...tire pressure to high. That was at about 38 hot. So i'd say you want it below that for sure. 34-36 hot sounds about right.
