Can't speak for either option; I'm still rocking the originals over here. But FWIW I looked around and found out that even though the lengths and strokes are the same, there's apparently a difference in force depending on whether or not the car is equipped with a trunk-mounted wing/spoiler.
With wing: 54 pound struts
W/O wing: 39 pound struts
Kinda frustrating that some listings don't mention which application they're for, or the specs on what you're getting.
