I'm pushing. Help me turn in.

Ran 25psi front and 27 psi rear. How low can I go?

I'll loosen up the front bar as well. Workin' on tiars right now. (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif)

I suspect part of the issue is running the "R" Hoosiers for autox. You will probably never get enough heat into them to get normal Hoosier grip. The "A" version is compounded for autox and should heat up extremely quickly, although would be worthless on the track.

FWIW as Andy mentioned I typically run them in the 38-40psi hot range, which equates to 30-32 cold, plus or minus. Other -R tires like Kumhos seem to be happy with significantly lower pressures (<30psi), I guess due to the different belt/sidewall/compound construction.
