I like the looks of the WRC rear wing too, trying to get as close to making my car look like the 555 SWRT cars as possible, but wasn't too sure about having the rear wing half on, and half hanging off the boot lid.
Especially when on the real WRC cars, they have a sign saying not to use the rear wing to shut the boot lid.
Hence I got a replica 22B adjustable rear wing instead.
That really is one nice looking wing! How do you plan on mounting it? Are you planning on hanging it off the back like the "real macoy" (I think I spelled that wrong)? Make sure to get us some pics once you've installed it.
