What a re good cold/hot pressures for stock C6 Z06 RFs for HPDE?
Considering doing an HPDE on GY RFs. Anyone recommend a starting pressure and ideal pressure when hot and with factory alignments?

Recently did an hpde at putnam park. Started the first day with cold temps about 32. gradually bled off air over 2 days as track and tires heated up. My neighbor running c6z06 like me was on Michelins, and kept telling me to run 26 in fronts, and 28 in rears. He corded one of the fronts before the day was through. I felt like my best laps were in afternoons and tires at about 29 in fronts and 30 in rears. When I went lower, it seemed the tires got greasy. What tread depths are you starting out with? jERRY

I would think low 30's starting out..but ultimately with the RF design you really won't notice much difference in grip/ride quality.
Its the R-compound tires that are very tempermental to PSI swings.

I run the 29/30 works good.

For a ZR1 you definitely want 28/26 which is what we did at Putnam.
