Updating the Cal Club supplementary regulations can bring some positive changes and this conversation is a step toward making improvements.
I am not sure you understand the point of my post above so forgive me if I am wrong about that.
First we have many auto-x 911s in Southern California that have modifications that are not far from HCS allowances. I enjoy seeing them run and I know several of the drivers. We attend meets and go on drives with some of them. I would love to see 20 of them run in HIST1 at every event.
My point is that the PAX for HCS is so soft it is not in alignment with any SCCA Solo2 class in the National Solo rule book. HCS is not listed in the Solo2 rule book and the SEB does not maintain Heritage Classic. The CAL CLUB 2020 Supplementary Regulations do not have an allowance for driver's to use HCS. It is up to the regions to adopt or reject HCS in part or in whole. As presented by Howard Duncan, HCS was created as a street tire scratch class for consideration at only the local level and a stepping stone to PREPAIRD to appease the former GP participants. This is a very different charter from HIST using Solo2 PAX in Cal Club even if HCS is presented as place for pre 75 cars to run. HCS if adopted is really a catch all class like XP or CST. The motor modification allowances are for PREPAIRD classes.
The modification allowances within any rule set encourage participants to use the full set of modifications otherwise the allowances would not be listed. When people make modifications outside of the allowances that becomes abuse and that is what a protest is for. It is not abuse to build a car using the published rules in the SCCA rule book and or CAL CLUB Supplementary Regulations. If someone builds a car that does not fit a class the car falls into a catch all class like XP or CST. If HIST1 drivers want to run scratch in a go for broke fashion and make modifications with almost no PAX adjustment over stock that is OK for them to want that however, this is a different charter from HIST in Cal Club. The region year end PAX listing will be very interesting. A change of this magnitude requires review and we are doing that now.
I hope that helps.
