wow they look awesome!! how much did it roughly cost you overall? (valance, fitting & sprayed)
I got it very cheap as I was the first (or one of) to use that particular company. The real cost comes from the fact it needs high build primer first to cover the black plastic mottled surface. They still sell on eBay (my car is their photo on listing) If you wanted sides and front splitter too you could get a deal - speak to them direct is best.
I fitted myself with my brother.
Not sure on the paint but the standard valance unpainted from TPS is only about £75, priced one up this week cos mine has a nasty split.
I also looked into removal - looks really easy as it comes away without removing the top half of the bumper.
Getting off with top part on car is pretty easy, but easier to fit new one if top removed too due to the flexing in the centre when trying to apply pressure to clip together
