Sachs+APEX are good enough for me now. Will see when the Sachs kaput eventually. As far as comparison with stock shocks/springs is concerned, definitely one nouch ahead. I tried a e46-328 w/ stock shock/spring and felt enough body roll on a descending bend whereas the e34 w/ above combinations went thru as if it's a straight road...

Both w/ low profile tires.
535i, Bilstein yellow needs to be ordered in advance, from Germany? I thought there should be enough demand locally.
