This league is a simulation league (no driving, just send in a car
file and races are simmed). Not a lot of effort involved for
membership, but with 40 cars or so, makes for interesting results.

This is an N4 driving league. Sunday nights, 50% races, open setups.
Currently in the middle of the race schedule, so now would be a good
time to join up and get acquainted with the other drivers before the
next season starts. A great group of guys in this league.
