Will you guys chime in on how you like the springs?
How long you've had them?
How's the ride?

I've seen most people are content, just trying to get some opinions before go for it.

I had the H&R sport springs installed on my '14 435i xDrive not long after purchase. The resulting ride height put the xDrive where I think a sport coupe "should be," while retaining the winter driving advantages of all-wheel-drive. There is about 1" of wheel gap front & rear. Regarding ride, in my opinion the stock dampers are too soft for the springs. Both compression and rebound happen a bit too quickly on bigger rolling frost heaves and bumps. It's not horrible, but I personally would like more damping to eliminate the quick "bounce back" after bigger compressions. Some sharper bumps immediately produce a "thud" - possibly a product of the progressive spring rate with the light damping of the stock struts.

Recently I hit a monster pothole - a product of the very strange freezing/raining/thawing cycles we're having here this winter. It was horrible and I put a slight flat spot on both driver-side winter wheels (tire beads are okay) and broke the lower tab on the front strut, causing the strut to slide in the lower pinch bolt/clamp and dropping the ride height about 3/4" on the driver front.

I'm wondering if I would have sustained such damage had I been running the taller & softer stock springs. My guess is I would have, as it was an exceptionally bad pothole. I'm deciding now whether to replace the stock struts and shocks with Bilstein B8s, which are supposed to be 20% stiffer than stock hence, theoretically better suited to the H&R springs; or, go back to the stock springs with an OEM replacement strut.

I've been looking for opinions as well and came across this.

Great review. Thank you for the link. Given the relatively small difference in price I am going with coil overs. The main reason is that I have friends who are unhappy with the drop. The drop can be also be inconsistent. I am waaaay to OCD so having the ability to adjust the height is necessary to keep my sanity. This car is also my only car so I use it for ski trips to Mammoth. I intend to raise it a bit so I can install chains and to deal with the snow and ice.

Nice
I'm in South Florida, not many ice issues here. Haha

I think I'll be going with the Sport springs and then if need be adding the Bilsteins
