I didn't take a ton of great photos but I can confirm, this was a pain in the ass.
Getting the bumper off is easy. I had a new grille so I didn't have to remove that but I have to imagine that would've been impossible given how it clips in and how hard it was to get the new one in. I re-used the stock spoiler, fog lights, fog light flares, fog light trim and the two big structural pieces that the fog lights screw in to.
With the benefit of not needing to retain my stock bumper, I dremel'd and/or cut a lot of the bumper tabs holding the plastics on and they were still difficult to remove. Got everything off but each piece either snaps into the next piece or screws on top and it's all very painstaking trying not to break anything. Took about 5hrs from start to finish, which included having to get the cutting wheel out to remove some stubborn bolts from the aerofabb splitter so I could install the new one into the stock spoiler. Also realized one horn was not bolted to the bracket, just kind of was swinging around from the wire. So I got that bolted back up. Also got some loose belly plastics re-secured better so they don't flop around as much.
Paint on the new bumper does look nice but there were three areas where they didn't prep it very well and there is dirt or something under the paint. Wasn't pumped to see that after rolling around on the driveway floor for a few hours but they are small imperfections and overall the bumper does look way better than the one I took off. From 3ft you'd never see them, the bumper and I were very intimate for a while so I noticed.
So the lesson here is: don't assume that little piece of debris in the road will fit under the car. It won't. It'll break your front grille, which will then cost you lots of time and money replacing everything.
