it's not bad to install. double sided tape and some self tapping screws is pretty much it. they have the instructions on their site if you wanna look it up.
If I part it I'll keep the sides and I have someone here that wants the spoiler. I would sell just the front and rear together for $150 plus shipping. or $100 each plus shipping.
