I Figured I would post a quick write up of my thoughts on the B14 coilover kit for xDrive

I had previously read that some people had issues with the rear sitting low. As well we know the issue with negative rake on these cars.

I’m very happy with this kit and how it turned out. Maybe this can help someone in a similar position trying to decide

Initial setup: Eibach RWD springs and stock shocks. Car sat low enough for me but with some negative rake. Stock worn shocks drove pretty bad in retrospect. Lots of hard bottoming out. The front strut mounts were pretty compressed as well with 100K miles on them

B14: Much more equal drop front to rear. Drives solid. no more bottoming out. I really don’t have anything negative to report

• Bilstein B14 # 47-269095
• Front Top Strut Mount Bearings
• Front Strut Carrier Gaskets / Pinch Bolts
• Rear Spring Lower Shims / Bumpstop Cups / Sealing Grommets
• Rear Shock Mounts Upper (Monroe HD)
• Rear Shock Mounts Lower (Monroe HD)
• Also did Z4 2pc front rotors, pads, painted the calipers, and pressure bleed

Some random pictures below and showing the ride height
** I went full drop in the front and fully raised in the rear

I live in Michigan and most of the roads around here suck. The car is way more forgiving

Thanks for the writeup! I purchased B14s for my 2011 E91 xDrive and waiting for the kit to arrive.

I love it. Soaks up the hits on crappy roads way better then the stock high mileage shocks. Night and day really

I have no negatives considering the car is a daily driver

Nice! Are the E91's quite a bit heavier in the rear? Just wondering

Yes, from what I've read, E91s are heavier in the rear.

I've been watching a couple of install videos as I'm planning on doing this myself. Did you need any special tools, especially Part B in the front strut diagram? Some videos show a special strut nut socket when installing the coilover. Just wondering if I need to purchase that.

Where at in Michigan are you? I'm looking at my options to change up suspension and would love to maybe take a ride.

I'm in the Kalamazoo area.

Finally got the B14s installed on my E91 last week and I'm loving the ride quality so far! I can feel that it's a tad bit stiffer than stock not much of a compromise for daily use.

Definitely plan on getting these for my e91 as well, and plan on adding ground control camber plates to the front to get it dialed in perfectly
