tire pressure / Nitto 555R's
I was going to take the camaro to the track tonite and see how the mods are working. I changed from 16" stock GM chrome rims to some 17" rims. the back rims are 17x11's with 315/35/17 Nitto 555R's on them. What tire pressure should I try to start with? I haven't ran the car since I installed a Vig 3200-3400 stall and it is tough to get it to hook up. Any help would be appreciated since I don't know what the hell I'm doing.

Don't get too excited, the additional hook probably won't outweigh the much heavier wheels. I found this out the hard way when I switched from 245/16's to 275 555r/17's. That extra weight is an MPH killer IMO.
What you should do is use the 17's on the street and strap some MT drag radials on your 16's. Then you'll have hook and MPH.

I run 18lbs all the time everywhere (daily driver). Any higher, they wear the centers and traction suffers, any lower and it's sloppy with worse traction on the street. Don't know about the track.

I drive my car to the track so the tires are kinda warm so I set it usually 2 pound lower than desired then the burnout brings it to where I want.
