David,
Do you have the Alpina specs for rebuilding the Bilsteins? As well, do you have the spring rate for the Alpina B7 Turbo springs?
How would you describe the ride/handing difference between the Alpina set-up and your current set-up with the H&R and Billy Sports?
The reason why I'm asking is because a the present time I'm rolling with a Dinan set-up on my e28 M5 and I anticipate that sometime in the future will want to replace/upgrade the suspension.
