Bilstein B8 or Koni Yellow for F30 w/ H&R Sport Springs???

I have a 2013 F30 335i with H&R Sport springs and looking to get new shocks and struts. What do you guys recommend between the Bilstein B8 and Koni Yellow?

Any pictures of setup would be greatly appreciated.

If longevity is a concern, go Bilstein.

Koni Yellow unless you don't mind a pretty stiff ride, then go with the Bilsteins

Hmmm... so Koni won't last long? Is it because it's not cut shorter like the bilstein?

Before adding aftermarket the shocks, what are your impressions about suspension behavior with H&R Super Sport springs and OEM shocks? Jarring ride? Excessively stiff? Other?

I'm using OEM shocks with H&R Sports not the super one. When I first got them years ago ride was pretty good. Now it's just bottoming out here n there. It's been so long I don't remember how it was after I put the h&r on honestly.

You are right. Should have read the original post one more time. H&R Sport springs ...

I am not a big fan of mixing and matching shocks and springs not designed to work together. For me, coilovers - especially ones with individually adjustable compression and rebound behavior - represent the better option because you will have the ability to tune suspension behavior and accommodate both comfort preferences and road conditions. Of course the cost is higher.

Lower cost coilovers (yet a quality product) include KW Street Comfort which performed very well on my previous 2013 335i - same car as yours.

If the choice has to be made, Bilstein B8 shocks get my vote.

Thank you for the input. I couldnt find much on the street comfort for f30, but are you able to adjust the dampener on the coils? easily accessible or would you have to remove wheels?
