After throwing on the H&R springs, I've come to the conclusion that stronger shocks/struts are certainly needed.

The only real option are Bilstein HDs. I run them on my 135i (w/stock springs) and love them.

They don't make Bilstein Sports for the X1 (not even special order, like the front HDs are anyway).

Do we think the HDs are going to bottom-out like the stock shocks do on the H&Rs over large bumps at high speed?

Since the H&R springs are "designed" to work with the stock shocks (ha), I'm thinking the HDs may be fine. I'm hoping the added stiffness of the HDs will be able to keep them from crashing on the internal bump stops....but I'm not sure.

I'll be pissed if they are prone to the same bad behavior as the stock shocks are, after dropping $650 on them and waiting 3 months to get the fronts produced/shipped.

Any thoughts? I'll post comments after I get them (first the rears, then both).
