i have the s281 very nice wing i love mine, tip if you get it on the 99 up you will have to run double sided tape on the back part where it goes along the back side of the trunk did that on mien to keep it from moving been fine for over a year.
I think the wing all depends on how fast you plan on going... Unless you just like the wing style. If you'd go with a wing I'd got with a Cobra R wing.
