Anybody get into dirt track racing?

I might get to drive a UMP superstock this year (pretty much like a late-model with less power). Anyone know what psi to set my tires up at and a good gear ratio? Probably run at Paragon Speedway in Indiana. It is a 3/8 mile high banked oval. It gets really slick later at night right around B main and feature time. Any help or info would be great
