I have an e-tron which in the UK is fitted with "Dynamic" suspension from the factory and there were no other options from the factory . It is soft and wallowy and did not match the performance of the car ....
I looked at various options including retrofitting mag ride but this appeared to be a complicated scenario.
I have fitted B12 kits to my previous cars and liked what they did to the ride height and handling . The kit consists of a set of Eibach Prokit springs and Bilstein B8 shocks.
I initially just had the Eibach Prokit springs and new top mounts fitted as Eibach said they will work with the factory shocks. This may of been the case for brand new shocks (mine were at 30k miles) and nice German roads. It was not the case for my shocks and UK roads... They made the car handle much better (it cornered flatter and was much more planted), but the ride was embarrassingly bouncy ! The shocks could not control the springs....
You may have more luck with the Sport S-line or S3 stock suspension as I guess the is firmer from the factory
I then ordered a set of Bilstine B8 Shocks. These were fitted and have brought the springs under control. The car now handles as it should of from the factory !
The car is now at a much nicer ride height, it corners flat and is not crashy. The difference is night and day between The B12 kit and the factory Dynamic Suspension The car is able to put down its power a lot more effectively .
Ride Height
This was never my mission but the car looks a lot better now, with no issues so far with speed bumps etc .
Stock Dynamic Suspension (measured from bottom of rim to wheel arch with standard 18s )
Front:625mm
Rear:620mm
Eibach Prokit Springs and Dynamic Shocks
Front:595mm
Rear:598mm
B12 Kit
Front: 595mm
Rear: 590mm
So overall a drop of 30mm to both the front and back with the B12 kit.
TotalVAG
They fitted the springs and then shocks they were brilliant, really knowledgeable and friendly. I highly recommend them .
