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?
i like right around 18 with mine.
I do 18 if I plan on racing.
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.
sounds like a plan. 18 it is and ill keep you up to date on hook
:goodluck:
first time ever so i might need it :xfingers:Quote:

I start at 18 and work my way down with those.
well i was set and ready to go but it is 100° today and 107° with the humidity...the track temp was near 130 so i decided to wait on going today

Did you have dr's with gears before the stallor stock gears? I ask because I tried something similar with some v710's at the track and my car would not have any of it.:suicide:Quote:

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:lol:
Sort of hoping that 12.5 was before the stall
Don't forget the average DA here in PHX is 3500'. Take about .3 seconds off for sea level...Quote:

Gotta find me a used 10-bolt.
If your still looking next spring, I may have one with less than 25K to part with...depends on how my mod budget looks over winter...and how bored I get when there is 6' of snow blocking the WS6 into the garage.Quote:

But is it mainly a concern when high speeds are maintained for some time? Do you get away with it while drag racing because you only have real speed in those low pressure tires for under 10 seconds per pass?
i run around 15 or so at the track and it hooks great enough to lift the front tires
Manual refers to a street tire.Quote:

The tires will grow will running down the track. Before I head home I put street pressure back in the tires. I have driven with low air in them before on the street and highway. It is the last thing you want to do.
Managed to forget to air up the Hoosiers (13-14 PSI) for the ride home once.Quote:
