AJ,
I think that you wold be better off with the actual spool kit for the cyclone, as well as the pro diff kit for the rear. I will bring mine out on Sunday if you are at DHW as I have the spool kit on mine and you can check it out.
On another note though how are you guys balancing your S left to right? Is useing two scales the only real option with the stock shock towers? I know on some of the touring cars there is a hole in the middle of the shock towers that you can run a string through and lift your car with to see if your car is balanced left to right.
