Hiya mate, where are the stepper motors? Also, do you know if the these actually work - as in, you've seen them wired up working with the racelogic ECU? What happens if you don't wire it all up, and just stick them on your car - the fronts are just 'normal' in this respect, yes? Finally, give us a ball park figure, mate, I wouldn't want to offend unknowingly!! ( knowingly is a totally different matter! )
