How are the sun roof deflectors mounted and which brand is the best?

Thanks, T

I have one for sale.
the OEM for really cheap PM me for details.

tfrost...just so you know, there are threads in here discussing how the OEM sunroof deflectors DESTROY the paint on the roof after only a few months. If you go back about 7-10 days you should see one with at least 10 responses from different people all saying the same thing...DON'T PUT IT ON! I took mine off after reading it and honestly I don't notice a big difference in wind noise at all.

But to answer your question...the OEM one attaches with 2 brackets and screws. The brackets fit into the sunroof lip and the deflector screws into those brackets. There is no drilling or screwing into the car itself required.
