James, adding the larger ground wire as well ,will cover two of the "Big 3" for electrical upgrading. The third being a chassis to engine upgraded wire. I've seen people add one of the alt rewire wires between the vertical alternator mounting bolt to one of their strut tower bolts to acheive one of the Big 3 requirements.
The battery to chassis is easier with something like a yellow top Optima battery, where you can mount the ground to the top post.
