EDC is the Electronic Damping Control. EDC is relabeled as the M-Adaptive Suspension on the F30. It is different from the 3 Modes: Eco, Comfort, Sport. The Modes adjust trottle response, steering stiffness, etc. The EDC adjust your damping. EDC by default adjusts with the different Modes, but you can customize it through iDrive (I think).
With the KW V2, your damping will be adjustable manually on the top of the strut. V3 will have the rebound adjust at the bottom of the strut along with the damping adjustment at the top.
If your F30 has EDC and you wish to get the KW v2 or v3, you need to get the EDC option. It comes with a module to delete the stock Electronic Damper Control without throwing a code. That's why it's a couple hundred more. You "can" get the coilovers without the EDC delete module, but you'll probably get errors on iDrive.
PLEASE NOTE... I do not have a EDC F30. I might be wrong with some facts that I posted, but I'm pretty sure it's right.
One last note. I wish I could return my KWs and get some CKS coilovers instead.
Thanks for the info.. ^^^ also, why would you like the CKS over the KW's?
