2009 PAX Factors

The PAX factors are derived from comparisons of the best drivers in the different open SCCA classes in a selected series of events. Thus a PAX factor is a sort of handicap with a PAX of 1.000 being for the fastest class of cars (A-Modified). Use the table below to find the PAX factor for your car's class. The official PAX Web Site contains both present and past PAX factors.
