If anything I recommend a direct clip in replacement. The fog light lower grille fit perfect. The vent grille takes some adjustment to make it to ones liking. I just wish Scion made a fender liner vent behind the vent to tunnel air to the brakes like on Lexus, some Subaru's, and BMW's. I bought this kit because it was made for our boxes with fog lights.
The top grille didn't bother me like others. The vent and lower grilles bothered me because of the lower different designs. I wanted something different yet subtle not extreme and the kit got the job done.
I could see why you would dislike them. These grilles personally work best dark and on dark colored cars because of the way they install.I have 2 sets of fig grilles, black and orange. I did not like the vent grilles but the upper and lower grilles are awesome.
I just might have to. Funnel the air somewhere other then the fender liner itself. Hopefully this will help prevent the occurrence of the fender liner ripping off.Sounds like a project to me....
I like how you think. Cut a square/rectangle or drill a large enough hole in the liner and cover it with some grille mesh. Sounds like a plan.you could drill air holes in it.
