2014 spoiler fitment???
 

Has anyone tried or does anyone know if the spoilers off the 2014 SS or RS can be fitted to the 10-13's? This is pretty much the only thing off the "refresh" that I seem to like.

Doubt it will fit, the rear trunk was re-designed to have a molded spoiler of sorts. BEst option will be waiting for an after market version that will fit on our earlier model years

Doubt it would fit, maybe it would be possible to swap the 2014 trunk lid w/ spoiler?

Yes, the trunk lid is a direct replacement but was trying to stay away from that option since I have a lot of custom mods not to mention the custom paint just on the trunk lid. The molded spoiler on the lid isn't the one I was curious about, its the bolt on version. if the bolts line up, in theory it should be a direct swap out for me.

With the shape of the deck lid on 2014's I don see it bolting up properly at all on a 2013 deck lid. You will probably have to just try it & see how it goes because I doubt anyone else here has tried it.

has anybody try it yet?

Has anyone be brave enough to try this yet?

You better relook at that, the trunk lid may bolt up but it is not going to fit correctly around the tail lights or meet up correctly with the bumper.
The spoiler will not fit a 10-13 because of the difference in shape of the 14 trunk lid. The bolt on spoiler on the 14 is made to follow the contour or the built in trunk spoiler.
