ok i have a evo x (non aero kit) and the passenger side skirt is sagging underneath the front door.. but no where else.. i tried to put some more double sided tape but that hasnt made it stay up.. anyone have any ideas how to fix this?

 

Is the car still under warranty? If so take it to the dealer. There are little body clips that hold the side molding on correctly. You may have to take the whole molding off to correctly fix the problem....
