I'm a new WSCC member and just planning to autoslalom this year. I have a '06 Pontiac Solstice. In the future, I know I can't do any track events unless I have roll protection. I'm kind of adverse to adding a roll cage because it's a daily driver and I do some touring, etc. I'm wondering if there any any after market hardtops that would allow me to do time attack? For example, this company has a hardtop with a 'club racer' version. Would that meet regulation requirements for time attack?
