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
PASM-equipped 997s use the factory ride height as a reference point for the adaptive damper control — lower the car with springs alone and the system can misbehave. Pro-Tronic recalibrates that reference so PASM keeps doing its job properly once the car is lowered.
Technical specification
Function: Recalibrates factory PASM after lowering
Fitment: Plug-and-play module
Pairs with: Eibach Pro-Kit lowering springs on PASM-equipped cars
Warranty: Eibach 5-year warranty
Part number: AM65-72-007-01-22
Fitment
Porsche 911 (997), all engines with factory PASM — 07.2004 to 12.2012
Do I need this?
Only relevant if your 997 was ordered with PASM. Cars on the standard passive dampers don't need this module — the Pro-Kit springs alone are the right call. Check your options list or ask us to confirm from your VIN.
Fitted alongside your spring upgrade in the same visit — no need for a separate booking.
