Absolutely is. My mechanic-friend just bought his skirts and splitter a couple weeks ago for his Sky. Took a little bit of time to get the parts made and delivered, but it got done. If you give Norm your VIN, he can paint them for you, too. Norm's a small team but his work kicks ass.
Note that if you get the side skirts, you'll need a mechanical fastener (at minimum) because no matter how damn clean you wipe things down, that stupid double-sided tape never holds as well as we all wish it would. It just doesn't. It's not meant to maintain a fastened part like that for more than maybe 2 years, 3 if you're lucky, especially if your car sits out in weather every now and again. So what happens is, the double-sided tape gradually stretches into disconnection until you do something more about it or just reinstall with new tape repeating the process. For me, I eventually broke down and used a bolt on each side. I drilled and installed it myself and I think I saw my life flash before my eyes before I was done doing it--I swear I still feel PTSD from it--but I did it and I'm happy I did. It went over better than I ever could've hoped. With that combined with a little decoratively-applied automotive ATV along the long top seam, it looks great and is still holding strong and it's been about 4 or 5 years now.
Norm is great and you'll love what you get. At one point, he floated the idea of making some wheel flares but I guess he never got those produced.
