hi, I am the proud owner of a 1994 k11 and am considering lowering it, i am going to do bilstein b4 shocks all round and apex lowering springs but I'm not sure if 35mm drop is too low or weather the shocks allow for a 35mm drop
If the Bilstein dampers are the same length as standard dampers you'll be fine. I'm on Kilen lowering springs with standard dampers and feel it works very well.
I used to run the Bilstein Streetline kit (apex 30mm progressive springs & I think bilstein B4 struts?) with whiteline swaybars, gives a good firm controlled ride. will preferably need adjustable panhard to keep the axle centered or else the alignment will crab.
