The GT 2008 has M12-1.0 not sure if 2011 is the same. There is a valve with M10 threads instead of the 1/8 what I got what made it more difficult to adapter it, but NAPA has them if you already got a 1/8 valve
 
I know super old post but the Centric 130.61142 lists the front port as a M12-1.5 and the rear port a M14-1.5.
