How to modify the GT500 front spoiler to fit the GT Tools needed: Rotary tool with grinding and cutting wheels Jigsaw Stubby Philips screwdriver 7/32" Socket or wrench Drill with small bit (I used 5/64") Materials Needed: Body screws (Autozone) Body fasteners (Autozone) GT500 Lower valance (got mine from Ford for $65) Cut the yellow area as noted on the pic. Be sure to cut behind the front most ridge leaving the tabs, as this edge will mate up with the car. When you're finished cutting, take a few minutes to test fit the lip piece and make sure you don't cut too much. I ended up taking it on and off 4 or 5 times to get it just right. This step takes the longest. When you're ready to mount the peice up, undo the little bolts on the bottom of the car below the license plate (2) and below the the outer edges of the grill (1 on each side) with the 7/32" socket. Undo the top screw in the inner fender and use this mounting point. *Right before you mount up the lip, you will want to cap the holes that will be visible with the body fasteners. The holes on the lip don't quite line up with the holes on the inner fender, so I drilled on additional hole in the fender well (each side), and used a body screw to fasten it down for extra strength. Next utilize the bolt holes on the lip to fasten the center section up to the car. Thats it! Some people will gripe that the section visible in the center is ugly. I'm working on a way to cut some strips of plastic or rubber to clean up the edges and visible sections. Haven't got that far yet. Very easy project, and recommend it to anyone looking for a GT500-esque lip for not a lot of $$$. Bear in mind, the pics that I took show you the most un-flattering views of the lip, walking up to car you would have to know what you were looking for to see the cuts.
