    Bilstein B6 with lowering springs ok?

    Hey guys,

    I am trying to find out if it will be ok to use lowering springs on the Bilstein B6 shock. I understand the B8 offers a shorter rod for this reason and I do not want to end up wearing out my brand new B6 shocks for a stupid mistake. I have been reading through forums of people who have used B6 shocks with lowering springs that would lower no more than 30mm and it was ok, but I was unable to find anything from Bilstein themselves. Anyone have experience with this? I have an E32 with the horrible E32 gap up front, giving the car a reverse rake. I wanted to go for the B8s and springs, but at the time, I needed shocks quickly and did not have the extra money to spend on springs as well.

    My main concern is wearing out the shocks prematurely due to them not being in their "Ideal" resting position, but not sure if this applies to the Bilstein's design.

    If the shock shafts bottom out before the springs full compress (coil bind), that will be bad for the shocks.

    Mild lowering springs are usually "ok" with B6s, I have some guys that prefer them with the milder springs, but as you even stated if you're going to get "low" B8s are much much better suited.

    I lowered my E32 735i with H&R paired to Bilstein Touring (B4) so I guess you could also use the B6. I assume they are the same length shaft-wise. My setup rides nice, still comfy. Firm but not jarring.

    Bilstein B6 with H&R springs can be stiff, but not to the point that you will experience harsh ride.
