Is there any vendor that sells this kind of splitters? (like eclou made a while ago)?

And do they really work? If it's carbon, more or less protective?

 

We can make them for you. We use the APR carbon wind splitter which is carbon fiber top then fiberglass underside. Since I have the 997TT here, I will drill all the holes and make the brackets. This can be a single piece all the way across or a 2 piece like on the red car. We have used these on many cars like our EVO VIII which was very low. It takes the scraping quite well. Your looking at $750 delivered.
