I heard they add 5 bhp.
Anyone wanna explain the purpose/benefit of these?
Please don't say they deflect the wind.
Do they lower wind noise on the motorway? Keep rain out when its raining? Help in the twisties because of aerodynamical forces forcing the car into the corner?
Zomg!!!! 5 bhp per side plus 10bhp per sticker on my car!!! That must be like... +52 bhp!
Yup 52iirc or 62 if your lights are on.
