Which is better, Stillen's roof wing or Duraflex® - GT Spec Style ?
There is a big price diff between both, not sure about quality and fit. Or, is there a better brand?

 

Search the sedan forum for titles with "roof wing" in it.

 

From everything I've heard, Duraflex is pretty much the "I can't afford something good so let me get it cheap" brand. They make a lot of knock off body kits as well. I do not have any first or second hand experience with them though, only what I've read when considering other items from them. Personally, I'd wait till you can afford something with known good quality.

 

Sarona makes kits for the Infiniti - I know some of the M35/45 guys have bought spoilers, Aero Kits, etc from them... I think they make roof spoilers for the G37 Sedans

Thanks, I'll check that site, do the search and skip that duraflex.
