LOL......you know what? I was re-reading your post again. I realize your question didn't say anything about the suspension. I think your question is there such thing as a HFP sedan, right? If that's your question, then NO. There is no such thing. I did a major conversion of my car. I love sedans, but like the bumper of the coupe. So what I did was did a coupe bumper conversion (I'm the first to do it). Then from there, I did whole HFP package. I got the suspension, front and rear lip kits, floor mats, and 8th gen HPF wheels. The sides skirts are actually replicas of the Modulo kit. Now when I install all of these mods, I wasn't quite happy with the stance. So I bought H&R springs but kept the HFP struts. This project car wasn't done overnight. It did take a few month to do. However, I did buy the car 8 months ago. Not too bad considering it's not even a year old.
I installed it myself. The dealership wont install it because of liability issues not because it's not compatible. It will work fine, trust me. If you're gunna try to install it yourself, it's pretty much easy. The rear suspension, however, is a bit difficult to do. I had to loosen up the whole arm to get the spring in. I got the suspension mainly because I wanted to get the performance out of my handling. But after a while, I wanted to lower it a bit more because the HFP only lowers it by an inch. My advice to you is make sure that's the ride height you want. If you want to lower it later on, then I would look into coilovers. With coilovers, you have the adjustability.
