keep rear and side skirts grey or paint black?
It's black in the inside . Does that answer the question ? Not sureI bought the Wald Difusser last year and never installed it because I didn't know if to pain the skirts as well. I think you should leave it grey. Did Rexspeed make this in full carbon of fiberglass with carbon over? If it's full carbon it would be a great deal since the quality looks good.
The oem defusser has to be trimmed in the center section so that it fits.how does it attach ( sorry for the noob question) do you have to "cut/ remove" any oem stuff?
sorry for the crude pic but if you look at the section i cut out of the picture is what needs to be trimmed/cut .Could you please more accurately describe this 'modification' required for the rear piece to fit?
