Sock / strut options for E82 Bilstein B4 VS B6 VS Koni yellows

[FLATBMW]

I got an incredible deal on a new set Dinan Performance Springs and want to install them in the very near future with new shocks / struts. My question is will the Bilstein B4 do the trick with these Dinan Performance Springs or do I need to invest in more expensive shocks / struts like Koni yellows or Bilstein B6?

B4 is more of an OE application and is better for OE springs. If you are using sport springs, you should use B6 or Koni Yellows.

Also, if you do go Koni Yellow, I would recommend getting the Dinan version of the rear struts - they allow the adjustment at the top without removing the strut. I think it's a little more expensive, but saves a bunch of time.
