I've got the full Ebay Chinese carbon fiber lip kit.
The fitment on the front was close, but not perfect. Had to bend and stretch it a little to get it to fit right.
The side sills fit perfect.
The rear fitment was terrible right out of the box. I had to modify it quite a bit to get it to fit right.
So overall, I'd recommend the front and sides, but not the rear diffuser unless you want to spend some time custom fitting it.
Pics for reference, hope it helps.
