well my GTB 2 has 14g wire stock I believe, could be wrong, i dont have it right now, and I like the size but I wanna cut them down to fit the esc shelf better but Im afraid to do that cause I dont wanna replace the wires. It looks goofy cause I have all the extra wire length tucked up above the trans. its not very clean. but practical lol also, not that anyone cares, but I make anodized 1/8" aluminum esc shelves that I sell if anyone is interested at all. I have them in all my cars, they dont flex like the carbon ones, easy to apply esc to them and look awesome. well enough of my own advertisement lol if you have a picture matt of your esc set up in your b4.2, I would be interested to see it.
