Yes, this is an excellent feature as it prevents the loading and unloading of the spring to adjust ride height. The only other system with this feature is the AST 4200/4250.
With the lower front height adjuster preloaded in the steering knuckle, are you able to adjust the ride height or do you have to loosen the main steering knuckle bolt to change ride height? If you switch to a Swift setup, does the front only use a main spring? If it uses a helper or tender spring then you basically lose the benefit of the lower height adjustment.
Did you compare the RS1 and DFV on the street AND track?
What are the max spring rates the F and R e92 M3 DFV dampers capable of handling?
Would definitely be interested in street/track comparisons!
