the stages are just how, for lack of better word, grabby the clutches are. stage 1 is pretty close to stock, stage 2 is more grabby and so on and so forth, the higher the stage the less drivability it has on the street for daily driving. also the higher the stage the less durability it has in most cases. for your application i would say stick with stage 1 or 2, 3 would be pushing it and any higher you would hate driving your car everyday
