Just a quick note on battery relocation. If the battery is relocated there is a minimum 3/8 inch all thread retention (9/16" wrench nut size). Some tracks are very picky about this as some people have simply placed a battery box in the back and bolted the box down. This is not allowed. Also if you don't have a trunk (hatchback for example) then the battery must be comletely sealed from the driver's compartment. Usually you can put it in the trunk, but if you don't have a trunk they will usually have a problem with it.
