RTH classification

[smason]

I'm looking for some information on RTH, RTG, etc. classing.
I think RTH is for HS cars with tires 140 UTQG or higher, but I haven't found this published anywhere.

Also, have the RT classes just been added for local competition, or are these part of the SCCA classing system too? I didn't see them in the 2013 SCCA rule book.

Thanks!

The R classes have been added to stock by the club, it is not an SCCA thing. SCCA nationals have a road tire class where stock vehicles compete on PAX adjusted time. UBC is using the standard .975 adjustment.

Every club seems to have slight modifications so you need to read up. Often there is also a PAX modifier also.

A lot of this will change next year and 2015 as there are some major changes to SCCA rules and classifications mainly affecting stock classes.
