This seems to be a great idea however the 6112s would not perform optimally. The valving is set for spring preload, typically the buyer is after lift/level so the valving was targeted with that preload in mind. Having the spring more relaxed will/could cause an undersprung/over damped feel. I know many that have done it, I recommend at least a bit of preload to mitigate the issue.i guess you grew into your bilsteins!
am i weird that i want 6112/5160 but at zero lift? i just want the improved dampers.
gonna send your friends an email and see what's up!
