I just found out today by calling FOX that the 2012 110mm fork is actually a 120 and can easily be converted by removing the 10mm spacer on the air shaft assembly (left leg). Took me about half an hour and now I have a 120mm fork!

2002-2012 & 2013 80 - 120 FLOAT/F-Series Travel Adjust

I played around with the settings and have found that running a little more sag and 2 clicks faster rebound is my magic setting. I'm 190 with gear and am running 80psi.
