Hi MFREAK.
AC Schnitzer provides 3 different solutions regarding suspension. 1st. one you only change the springs, 2nd. one is the conventional sports suspension, changing both springs and shocks and the 3rd. one being the DFC (Damper Force Control) which can be electronicly adjusted in 3 levels: Comfort, sport and racetrack.
I have chosen the conventional sports suspension as I have very good expirience with this solution on my 540. So no adjustment on mine, sorry to disappoint you.
However I am considering to put on the type 3 AC Schintzer rims in the near future.
Currently I am driving with the prototype of a new set of mufflers I have developed together with a danish company. Great sound I can tell you, real deep V8 sound, which you can clearly hear inside, when the car is running between 3-7000 rpm. The next version of the mufflers are ready next week providing more sound in idle mode and low rpm. Final version for sale should be ready by end of October.
