Almost anything that works on the '13 should work on the '14. I picked up a '14 coupe a couple of weeks ago and have already changed the wheels and exhaust. However, the supsension has been changed so any changes there are going to have to wait until '14 specific parts are released.
As @kgf3076 said most things that fit the 2013's should fit the 2014's. What I've been doing is looking at the online parts catalogues to see if the part numbers are the same between the 13's and 14's so I know the parts will fit. As mentioned the suspension is different though.
good looking rides - welcome to the forum
