From what I recall (you'll need to verify), ACS uses Eibach's F34 (3-GT) rear springs for their F31 kits. That spring has a higher overall load rating, but I don't think it's as long, which likely leads to the reverse rake.
Also, I had my OE F31 rear spring compared to my Eibach F31 rear spring at my suspension guru's today and they have about the same spring rate. My suspension guy said that's not too uncommon where a lowering spring company will only stiffen the front rate. |
Awesome wish it was in english. it appears the inner diameter is 60mm? What are you running and do you still have the reverse rake? I don't see how they can sell a kit with such severe reverse rake, currently in contact with ACS and seeing what they can do.
Eric at the US ACS told me he'd never heard of reverse rake and requested photos and evidence which he forwarded to ACS germany for me, still waiting on their response.
