I bought my 2011 GT/CS with the idea I would get back into Autocross without researching first. Classing killed those plans. The Mustangs and Camaros that used to be Cheap Stock (CS) got grouped with the WRX and limited on wheel width while I was gone raising kids. You couldn't get enough tire to put the power down in the new rules. Not sure where the GT350 fits but generally I think the Mustang platform has better classing in road racing. All this talk has me thinking about formula cars like F500 and F1000. Now going to research Yamaha R1 powered F1000s. That cross plane sound is addictive.
