If your M3 or M4 has factory adaptive dampers (EDC), fitting lowering springs on their own will usually throw a suspension fault on the dash and leave the electronic damping control confused about ride height. Pro-Tronic is a small plug-in module that recalibrates the signal so the factory EDC system carries on working properly once the car is lowered — no warning lights, no disabled damper modes.

Do I need this?
Only if your car left the factory with adaptive dampers (EDC). If it's on standard passive dampers, this module isn't relevant to you and you can fit Pro-Kit or Sportline PLUS springs on their own. Not sure which your car has? Send us the registration and we'll check before you order.
We fit this at the same time as your spring or coilover upgrade — it takes minutes and means the car drives properly the moment it leaves our workshop.
