Prepping my car for tomorrow's track passes, what psi should I run in my Nitto's (555r)
Some ppl have told me 22 is a sound number, any other opinions?

Yes. I agree with above. Start at 18 and you may even find going a little lower might hook you up better. Good luck and let us know how they fair out for you.

The time in my sig was with 3.73 gears. Best pass prior to the stall was 13.09 @ 108+ with a 1.9x 60'.
The 1st set was Motive. They whined like a whore that didn't get paid.
The 2nd set was Richmond. They started to whine after about 25 passes.
Next set was AAG (basically factory). They were quiet till I started to race again. After about 50 passes the pinion bearing bearing sorta welded itself to the pinion. This was the set I did the 12.559 with.
The current set is a factory set of used 3.23's that my buddy installed. I've yet to take them to the track (It's too hot to race these days here in PHX). I had them installed for the cruise to the LA Invasion. No noise over the last 1,000 miles or so.

Now all I can think about now is how to make my rear last with 3.73's
Sort of hoping that 12.5 was before the stall

Seems like installing gears always ends up with a whine.
Gotta find me a used 10-bolt.
