Thanks for the info...

So just to clarify; when you say 'if your car is lowered, go with the Bilstein Sport' you mean if it's lowered more than a stock ZHP? I assume I should be looking at the Bilstein HD for a ZHP w/ OE springs. It seems Bimmerworld has a better price than Bavauto.

Those Rogue Engineering upper strut mounts look good. Only $100, and I'd have to buy two of the OE replacements at $50+ each anyway... Plus they come with all the necessary hardware.

Is there any truth to the comment about Bilstein HD's raising the car? I don't see why they would. After all - it's a shock, not a spring.
