My 99 Z3 2.8 (53k miles) looks like it's sagging at the right rear (drivers side as I'm in the UK - and yes, it's raining). When I got underneath to have a look, the coating has come off both rear springs, although they physically look ok. The shocks look ok too. My local 'BMW specialist' told me all BMW's sag at the rear
So, need some advice!
Is the sag normal?
Could the springs be at fault?
Is it normal for the coating to crack off the springs?
