Before considering the wing removal you might want to read through this thread, it has a lot of good information to give thought to. Pay particular attention to the last post, the one that Brent made on 1/12/2008.

As far as anyone doing an actual wing/spoiler removal, I haven't heard of anyone doing it.
If you feel you still want to do a removal, taking the SRT wing off should be a simple remove, fill the holes and repaint. If you want to replace with a deployable spoiler, I don't know what parts you would need, but, check on what parts would be needed and put them in (not as easy as it sounds I'm sure). However the electronics wont allow it to work automatically without reprogramming. However if you reprogram then the car will think it's a N/A car and wont run right.
