How would the koni yellows/swift spec-r compare to the bilstein b12 kit? As far as handling, lowering and ride comfort?

The koni yellows struts and shocks are both adjustable? Do the front have to be removed to adjust them? Where is the adjustemnt actually made? Ive never seen a pic of a knob on them or anything.

It will have a much better ride quality with linear rate springs.

Yes, you can order the external adjustable option or the rear shocks would have to be removed to adjust them. Front struts are adjusted via a knob.

Hi, can you clarify again whether the 1"/0.8" drop is from non-sport or sport? In post #13 you said it is from sport?

.

Does that mean stock E93 sits lower than stock E92 because of the weight?

Swift said it's from standard so I would say their information is more accurate. However, I have seen sport drop just as much. It will all depend on the condition of your current springs.

These springs aren't meant for the E93.

So would these be recommended with the Bilstein B8 dampers? I'm torn between getting the B12 kit or these springs with some other dampers. Are Koni the best bet, or would Bilstein be a better choice?

They are fine with any performance replacement struts and shocks or OE so Bilstein will be just fine.
