All right gang, here's the scoop. With lots of great input and a potential class sponsor, the OSCA is trying to breathe new life into it's premier naturally aspirated class. Below you'll find the proposed rule set for 2006. In order to make this class happen our sponsor wants to see commitment from any potential class racers. They require a minimum of 8 preregistered racers before they'll commit to the 2006 season. This would be a significant step forward as the payouts for 2006 would be guaranteed. Preregistration would cost $600 for the season. This covers class entry fee but does not cover track fees which will be $40 per race. The payout structure has not been finalized but would be a minimum of $1000 to win. The deadline for preregistration is Jan 31, 2006. Any questions regarding preregistration please PM or email the OSCA. There has been much interest in this class and with your support, we would like nothing more than to see it flourish in 2006.
