Is the HHR still not allowed in SCCA events? Doing some research turned up some info about the regular (non-ss) HHR's not being allowed in sanctioned events due to roll over issues.....true?

 

Not sure about the official word on that, but I can understand some caution there. The stock LS suspension does lean pretty good when pulling a hard turn. I doubt you could roll it though. And its easily fixed with rear springs and a swaybar, but then its not in the stock class.
Interesting though the cobalt Sport and SS trim levels are allowed, but not the base LS.
