The adaptive dampers have different bump stops than the regular/704 suspensions. If you look at the pictures on ECS' site, it looks like the bump stops that come with the adaptive suspension are already shorter. I wonder if new bump stops are really needed if you have the adaptive suspension.

It's interesting comparing the Eibach and ACS springs. For my F31 the specs for the front springs look almost identical (unsprung height, coil diameter, wire diameter), but the max axle load ratings are a bit different (ACS is 10kg more). On the rear springs, the ACS rear spring specs match with the Eibach F34/3GT rear spring (unsprung height, coil diameter, wire diameter, max axle load, and max extended load). The Eibach F31 spring has 5kg higher axle rating, but less extended load.
