StreetWires GT10 Ground Terminal 1/0 AWG
The GT10 Ground Terminal is the bomb.com! Very well made and worked really great for my battery ground. I recommend installing it on a completely flat space and sanding down to the metal on the paint underneath it so that it provides maximum grounding (the screws alone will not be enough IMHO). To help prevent/slow rust of the sanded spot underneath, go around the outer edges of the GT10 with a small bead of clear silicone.
