I bought the parts from summit. If you want to run at the track, you will also need a battery cutout switch which can be activated from the outside of the vehicle. BTW, I would not reccomend this to your FWD car. Keep the weight in the front where you need it. You do not need 0 gauge wire. I believe mine is 2 or 4. Look it up at summit. I know Audio King has some and Napa (hopkins) did also when I was wiring key machines in our work van.
