Eibach Pro Vs AC Schitzer Springs

ASRman · 05-24-2019, 06:20 PM

Anyone compared these two springs back to back? Some say the ACS are just rebranded Eibach Pros whilst others claim there is a difference. Also strange that ACS are not willing to share spring rates of the their product which plays into the rebranded Eibach suspicion.

Currently have Eibachs fitted and honestly can't tell too much difference between these and stock CP springs despite the Eibachs apparently having softer spring rates.

Here's the link to AC Schnitzer's F80 spring kit TUV document. Compare the spring specs with the Eibach F8x TUV document. If the specs match, then they're rebranding Eibach springs for the F8x like they do for the F3x. If they don't match, then ACS is having Eibach make their springs a bit differently.

In addition to the spring rate change from the ZCP to Eibach springs, the ZCP rear spring is also progressive while the Eibach is linear.
