Just got done with my spinbrush mod, though I dont have a working car (

). But it seems to go much faster! The old magnets are about 3 times weaker than the spinbrush ones, which seem to be pretty promising (it better be! I screwed up a stage 1 blue, and a stage 2 yellow making it

) So now i have 2 extra sets of weak magnets and clips (if you need them, you can have them). How much does this mod help out? I can't wait to try it out!!!
