help with ground effects?

Can you put ground effects on a non ground effects car? If so what parts will I need and what will I have to do?

Re: help with ground effects?

you need the gfx, a drill with a bit, and the mounting brackets
it will require you to drill holes in you car so that the bracket can be mounted.
as i believe there are two different types of brackets, they look the same but the holes are in different places.

off of another car, im unsure to wether they are riveted or bolt/screwed on from factory, so youll either have to drill out the hole or unscrew/bolt them to get them off a donor car. there are no aftermarket ones that im aware of

The brackets are spot welded to the rocker panel and need to have the welds drilled out and then most people seem to say to rivet them on to your car. The majority of the rest is just drilling the mounting holes and bolting on.
I do not know about the Camaro front ground effect spoiler peice.

Re: help with ground effects?

Are you sure they are spot welded? The ones in front of the front tires (GM 10041503 and the other side) are bolted on the sides of the front bumper. The bolt head is welded to the metal bracket and then the body of the bolt goes through the ground effect lip through the fender and a nut attaches inside the fender to keep everything in place. Perhaps the ones behind those (under the door) are welded since I don't think you can access the inside of the panel. I haven't looked, but I'll take a look tomorrow.

If removing these very front bumper ones from a junk yard, bring WD-40. I got impatient and broke the screw bodies off trying to remove the nut. These weren't even all that rusted. Looks like I'll be welding new screws on to the bracket.

You are right about how all the ground effect pieces are held on to the car but I was referring to the angle bracket that goes on the rocker panel just under the door for support of the top edge of the rocker ground effect piece. Perhaps I could have been more clear.

Florida Gators-- I will be doing the same on some of my ground effects when I bolt the replacements on. Drill and tack weld a bolt in to replace the broken bolts and cut new flat bar and drill and tack for missing pieces(the front fender ground effect pieces I got do not have the bars to bolt them on).
