I thought it was an actual upgraded motor. My mistake.
I'm not an electrician, but I don't understand how relays help in this case. Relays are often used to shorten the run of the wires carrying the load. I don't see the switch as offering anything other than momentary resistance. Once contact is made, it's made. I don't see how this appreciably shortens the run of the load carrying wires, although it would certainly reduce wear and tear on the switch itself. If the wiring itself is compromised, obviously the kit would help that as well.
A gear reduction motor with more torque is what I'd like to see, although the motor in the videos in this thread certainly operates better than mine does. It's been awhile, but the replacement motor I have in now was just as crummy in operation as the one it replaced. I know the aftermarket (the parts store cheapies, not high end aftermarket) is generally about cutting corners where they can, so that isn't saying a whole lot.
