Note:
LVKC club rules and spec. are designed to create competition
and assist the local club members in maintaining a reasonable
racing budget. If LVKC club members wish to race in WKA
sponsored events at the LVKC track or to race at other
racing venues or other racing series they need to refer
to the regulations for those particular series due to
the fact that club options are always superseded by the
different racing series. (Refer to Rule, Section 4.9)
