Found this and chatted with them. Sounds like a safer option at a good price:

You're going to save $100 to buy a knock off piece. Seriously?

 

Pro: I like the fact that it comes prepainted, I did that with my Tag reflector inserts and they worked out great (and the only labor was me).

Con: My graduate degree is in fluid mechanics (did a lot of submarine R&D back in the day) and I am too much of a sissy to mess with the wind vectoring characteristics of the tail. It only comes into to play at very high speeds and at those speeds, or higher, I would hate to discover that I had a balancing issue that made the front end too lite.

My 996 started to get scary above 170 because it felt like the front end was about to lift thus causing the car to do a gainer (type of back flip), and my 991 has proven to be fast and rock solid at all speeds.

Remember: If it ain't broke don't fix it.

 

Not to mention, companies like Vorsteiner stand behind their products if any warranty issues arise.
