What autocross class do you guys run in?
 

I know most regions are different. Some are by the book cone nazis, some are more lax.
What class are you autocrossers running?
I know if you follow the book theres only one class, EM.
but I haven't really read anything prohibiting them from running XP.?
I know my local region is pretty lax. They'd probably let me run SM. ;-)

I was told XP due to weight and size of engine.
