Fuses, Circuit Breakers or nothing at all?

I just wanted to thank everyone for the replies. I am definatley going to use some sort of fuse set up. Some of the guys that I know that have been racing their whole lives are still old school die hards. If a fuse causes me to loose a race oh well I still have a car to race in and not a burned up piece of junk. Most of the wire I have is all 10-14 Ga. so I should be all right their. I have also used OO Ga. for my battery runs from the trunk to the engine compartment.
Thanks again for everyones support & coments
