Lowering an E92 M3

I'm planning on lowering my E92 M3, I heard of the springs from H&R. Will it affect the EDC function? What about aligning the car? Does anybody know where I can get Camber plates for the front and rear adjustable arms? I do not feel like wearing out the tires without an alignment. Thank you all for your comments.

I lowered my car with RDsport springs. They lower the most from all the companies. I still have EDC functions. I will align the car when my rims come in.

So the car can be aligned with factory parts? Or do you have to add camber plates and adjustable arms on the rear?

The H&R springs will not effect the EDC function and can be aligned to the factory specs after install with no need for camber plates.

Does anybody knows if Eibach is coming with EDC-compatible springs?

Edit: I answered my own question: Eibach P/N 20100.140 is their EDC-compatible Pro-Kit. No camber plates needed.

10mm is not very much? The H&R kit is 1" front and .6" rear which is about 25mm front and 15mm rear. Wonder why your mechanic recommended 10mm and above?

The H&Rs are fine, they are EDC-friendly, here's a recent install on factory 18s:







Vehicle is equipped with 15mm/10mm spacers.

Both H&R and RDSport claim to be compatible with EDC.

I haven't seen any reported cases to prove this is an issue. Then again, I'm running KW V3s on my own M3.
