String Theory Garage will be closed to the public from Wednesday, 29th July to Thursday, 6th August for our annual shutdown.
If you need to get in touch, please leave us a voicemail or send an email. Our team will happily get back to you when we return on Friday, 7th August.
Shopping online? Don't worry! Our online store will remain active! We hope to ship orders placed for in-stock items as normal during the shutdown. Anything else will be dealt with upon our return.
Thank you for your understanding, String Theory Garage Team
Eibach Pro-Tronic Electronic Damper Module — BMW M3 Coupe (E92)
If your car has factory adaptive dampers, fitting lowering springs on their own will usually throw a suspension fault and leave the electronic damping control confused about ride height. Pro-Tronic is a small plug-in module that recalibrates the system so it keeps working properly once the car is lowered.
Technical specification
Warranty: Eibach 5-year warranty
Part number: AM65-20-014-17-22
Fitment

Only relevant if your car has factory adaptive dampers — check your spec or send us your registration/VIN and we'll confirm before you order. We fit this alongside your spring or coilover upgrade in the same session.
