what psi do you guys run?

[echocluster]

i am going into my first auto cross race next week. what kind of pressure do you guys run in your zees? i am also going to do some drag racing at a track. would the pressure be any different in that situation? i have a 71 240 by the way.

Autox - I run 18 PSI with Hoosiers (bias ply slicks) and 23 PSI with Victoracers (radials).

Echocluster,

I'd suggest you experiment. My '73 with stock suspension and L28 seems to do better with more pressure in the fronts. This yields less understeer at the track. On the street I run 35/30 front/rear. At the track I've bumped it up another 3 psi all around mostly to try to reduce the wear on the outer edges. Again, remember my suspension is stock.
