I would do all those mods and not even think twice. The weight of the cable isnt that much and being towards the back doesnt hurt. I also wouldnt hesitate on the elctric water pump, There is nothing better in my opinion. They cool the car good and when you shut it off at the ice cream shop you dont have to get back in with 230 degree temps. As far as cal tracs I think people tend to use them on applications that dont really need them. My car makes pretty good torque and horspower and I just have a set of the xhd springs and a pinion snubber and it hooks on wet grass with 275 drag radials.
