That's

 IMO, those kits are primarilty for aesthetics just like the wheels in the pic. ;)  Look at the marketing hype.  There's no spec data on aero improvement just "Ultimate in design and aerodynamics" which to me means the kit has the lowest practical aero drag for looks not that the kit reduces total aero drag on the car.  They wouldn't sell if they were ugly. :)

Absolutely, just for the looks, not more.... I mean, I am not that stupid to believe, that this sort of aerodynamoc will add hp or something. Well, maybe on some racecar it will, but not on my C-Max haha

Not sure what you are trying to do. Can you show pictures?  I used Velcro so the spoiler could come off if I hit something.

Here is the front lip design I am trying to repeat (see this Focus - https://www.carid.com/gallery/ford/focus/). The only thing I do not like about it are those straps that seem to hold the lip. But hey, are these a must-have?

Hi everyone,

I am new here!

Wanted to ask, whether anyone of you folks ever installed a bumper lip on C-Max? If so, how did you mount it?

I've checked videos, and some people say that it is enough to degrease the bumper with special 3M primer and then mount it with 3m tape.

Some even say that the side skirts may be mounted the same way. But will it really hold the lip? Or it's still better to drill the bumper and install the lip?
