I have been digging on the forums for a while and have not found a definitive answer to what is the different between stock and sport suspension. Some say just the ARB's some say springs, some say both?
Anyone know? 2012 clubbie S w/ standard suspension.

 

The sport suspension was a $500 option and it was stiffer springs, different shocks and 1mm thicker sway bar both front and rear. Most people that ordered it didn't like it because it was too stiff and transmitted a lot of noise and vibration into the cab.. I ordered my 08 with the standard suspension and think it's great. I haven't changed anything on it, but one of these day's I'm going to get the new Koni Special Active shocks.
