I agree the type-r wing looks amazing on the 3rd gen tegs. I wouldn't go for the RSX wing plus it seems like a lot of unnessesary work, unless you are going to paint your car soon anyway.
There is a good place on ebay that sells a Type-R wing painted to your color code of your car for 228.00 shipped to your doorstep. Comes with everything you need for the install and it appears to be a great buy considering the dealership will charge you three times that. Mine is in the mail now, if you hang tight for about three or four days I can let you know how it turned out.
Here is the
link if you want to check one out. Wow, I guess he just changed his bottom line buy it now price but it is still a good deal. He has great feedback and has a ton of sales. Hopefully he is the real deal. Emailing and other correspondance has been excellent so far. We'll see how everything turns out. GL.
