Doesn't come with hardware - just wondering how the fit and finish was and if installing it is any problem - and how you might have installed it.

I bought and installed one last year. Got the CF one and it's very nice. Fitment is great. I went for the 2 X 2 twill to match the rest of my CF stuff.
Now, I had the advantage of this being a more or less exact replacement for a cf-over-fiberglass one that looked very similar. I drilled a couple more holes in the very front of the clam (underside); but I was able to re-use most of the other holes, which held the splitter on very securely. I bought all new hardware, though. One of the keys was using large, fender washers. I used those both under the splitter (on the bottom of the splitter) and on top of the clam. I used fender washers followed by smaller washers followed by the bolts. Along with the nuts, I used lock washers. I guess you can use nuts with nylon in them; but I used regular lock washers.
Even though I had pre-existing holes in the clam and even though I was able to mark the splitter through the holes with a Sharpie so that I knew exactly where to drill, I still had to make some holes a tad larger (I did this on the splitter and not on the clam) so that I had some wiggle room to move the splitter around slightly to get the best fitment before tightening everything down.
I've hit over 120 MPH multiple times on the track and there's been no sign of it coming off or breaking. I'm also running with the splitter "extensions" underneath on the left and right sides.
