Curious as to what exactly a "high speed autocross" is under the current SCCA rules. Used to be Solo 1, but I believe that's gone away. "High speed" doesn't fit in the current SCCA Solo rules (I just checked). So, is this some sort of track event or time trial? Or is Florida Region just making up rules as they go?

As far as I can tell, it's either a "Solo" (autocross) with SCCA-mandated speeds of low-60's for street cars, or it's a time trial run under the club racing program with a different set of rules, and all competitors are required to be SCCA members.

Calling this a "solo" if it's truly a "high speed" event, is either misleading in some way, or they're breaking their own rules.
