Darn. If that is the case I guess I could of just gotten some Bilstein direct replacement shocks & struts for the 540i instead of spending the dough I did. Oh well, I'm very happy with the purchase & like the heigh & firmness adjustability. Sorry, back on topic now...

Only a 40lb difference is much less then I though...

 

40lbs wouldn't be enough to give the height difference I'm seeing. I reckon it's sitting an inch too high.

 

Did you check if the front knuckle is out of position (the piece that slides over the shock where thrust/control arms mate up to)?

 

that's only engine weight. there are other components on the M5 to add weight.


the OP also didn't mention the year of their vehicle - vanos, non-vanos makes a difference, 2 mafs + whatever extra wiring the M5 has. are these weights for fully-dressed engines, or bare long blocks?

the earliest 96/97 540s were nearly 400lbs lighter than their end-model-run counterparts.

 

Agreed Matt, that would be more difficult to find I imagine, I just found a site that compared the two and felt that gave a reasonable comparison, I assumed they would be like for like, i.e. short engine or fully built etc.

 

Solution :

Stick an S62 in there
