This is Justin's NA that sees the road course and autocross and maybe other events that I don't know about. Maybe the pic is old, but I don't remember a lip on his car last time I saw it.
I would talk to him before making a move on anything because he can tell you what works well with what and what isn't worth getting, etc. Personally, I doubt an r-package lip will do much alone, and I don't know what it costs, or the GV, but you will probbably be more happy with a nice set of upgraded sway bars or strut bars if you don't have them yet. Sways on my car made a great difference.
