On a tight budget but Wana swap my shocks and springs. Gona get vogtland 50mm springs and new standard dampers. Anyone have any experiences of using anschler shocks from ecp?

you will need shortened dampeners with -50 look up bilsteins b8 or b12's

Na you won't mate. Loads of people have stuck 50mm springs over standard shocks. 50mm will only bring a vrs down about 30mm anyway.
