All I can say is just do this mod even if you don't need it at the present as it will be easier then when the bumper sag's or bow's.....When having my GHL's installed a couple weeks ago, I noticed how much mine rear had bowed from the heat off the old muffler's...The instruction's are worthless that come with them though. I bought mine from ecklers for about 60 buck's. Make sure all the dirt is out of the bottom lip's....make sure you have the right piece for the right side and it's turned with the curved side down...There's a small upward curve in the piece of fiberglass that should line up pretty close with the inside of both bottom vents....Put the supplied silicone on the fiberglass and drop it in the bottom, making sure the piece fill's the bottom lip first<<<<very important....Take a good swig of a cold beer and sitting on the ground behind the bottom vent left to right, work the far left section over the fiberglass and walk the lip down the end<<<take's a little patience and the right hand piece of the fiberglass is hard to pop in if you have much sagging or bowing.....take another swig and reverse while doing the right hand side of the bumper by starting on the right corner and working let....always working from the outside toward the inside.......This will straighten out the rear bumper or keep it from happening in the first place...

 

We need pics. Please. I would like to see these. I have heard of something that gets stuck in the vent area but I didn't think they would look that good. Is what your talking about different from that? TIA

 

I`ve been thinking about a set of these reinforcements also;

I AM THE KING!

 

Once installed, you can't see them as they fit on the inside of the bottom lip.

 

I went for the ACI reinforcements on my wife's vert, since they fit better than the Eckler's (tried both).

Nice tips. I have installed all the other screen pieces, but not the ones for the rear fascia. May have to consider these too.
