# I have an NA/NB Miata with the Kraftwerks kit, and the belt keeps coming off. Is there anything I can do?

The supercharger kit was designed based off of power steering, and A/C is present in the vehicle. If the vehicle does not have either system or is missing both, it will cause the belt to come off. You will need to purchase an idler kit or an a/c delete kit to have a pulley present so the belt can be routed correctly.
