YOU CUT your holes for Seat Seat Belt & Shifter
The flooring is INTENTIONALLY OVERSIZED - this allows for a little room for error with your install. So yes, you will likely need to trim the edges when you have the kit in place.
DO NOT CUT until you are satisfied with your loose fit - once you make a cut it is yours.
***ACC flooring kits CAN NOT be returned if you cut or alter in any way. If you think you will have a fitment issue or do not feel that you can install, let us know PRIOR to cutting. AND, make sure your vehicle, this listing title, AND the white box label all are the same vehicle
