Anyone out there that has the c6 chrome plated billet sills? Do you have to remove the factory sill? Does anyone know the thickness of these sills?

I have them.

I don't think its required to remove the factory sill, but I would HIGHLY recommend it to get a good contact so it doesn't start falling off. And the factory sill doesn't come off very easily...

I don't know the exact thickness, but I would guess somewhere between 1/8" and 1/4"

i didn't remove mine on my 2007, i just placed them on top and no door rubbing issues.

I removed mine. Not easy, but if you heat them up they peel off and then you need lots of Goo-Gone and elbow grease to get rid of the glue residue.

A little heat from a hair drier and they come right off.
Then stick on the new ones.

A little heat from a hair drier and they do come right off, but the glue doesn't! I guess if you're okay with just applying the new one on top of the old glue, but the glue is the hard part to get off...
