ACS designs it springs and Eibach manufactures them to ACS specs. Different products.
You might look at the 650 rear sway bar that people are using - it made a big difference, too, put it all together.

so what is the difference between ACS and eibach, arent they the same spec?
any use in 650i sways on OEM suspension?
