This table I created from the data out of the Bilstein classic catalogue with all known suspension / shocks setups for the 911:
Columns: Setup name, front axle, rear axle. The numbers are rebound/compression in Newton.
"Sportlich Strasse" means sporty road and is the stiffest/hardest suspension for these cars and not recommended for non trackday drivers. And on Targas/convertibles it should be forbidden as the body suffers too much on that.
