BMW B12 Pro Kit - Bilstein 46-180568

Bought this kit for my 2011 E90 335d, the quality and performance of this kit was spot on. Nice level between comfort and performance as well as lowering. This kit feels much more refined than the factory sport suspension, absorbs potholes/bumps really well.

If you want factory nice smooth ride not too stiff with a stances look no feather this is it

This kit is fantastic. Under $900 bucks for track ready performance. Struts have the Nuremberg Ring logos stamped on them. It’s more aggressive then the M3 suspension hands down and the car sits lower. I’ve had the cars side by side. After getting my 335d deleted and tuned I knew I needed to refresh the handling. I had this suspension along with new oem strut mounts Install on the front and rear. I used polyurethane top mounts in the back of the car. The ride is transformed. At 80K miles my stock suspension felt sluggish over uneven road conditions and over minor bumps. Handling that felt somewhat "saggy and loose." The Car would sink over the smallest imperfections of the road, especially during spirited driving. Literally I love this suspension it’s not too aggressive yet very sporty.

I have a 2007 BMW 335i Sedan with 120,000 miles, which had the original suspension. First, I should have changed this out at 75k or so, having learned what I had learned as a part of this process. The Bilstein b12 kit lowered my car equivalent to a 335is with the m-sport suspension on it. I have basically taken a car with standard suspension and given it a suspension better than the m-sport suspension by all reviews and accounts. I have driven a 335is, and I can confirm that. It does take 1500 to 2000 miles for the suspension to be fully broken in and the car to "settle". It will continue to lower as you get closer to the 1500-2000 mile mark. As long as you don't touch any camber related bolts during the installation, you should be ok without having to get a full 4-wheel alignment until the suspension finally settles and is broken in. However, you should get a 4-wheel alignment at some point in time after installation. This kit was easy to install as long as you have the right tools. An air gun is a nice thing to have, and probably a must if you live in a state where "salt" is used on the roads, during the winter months. Also, having the right kind of special sockets for the tops of the front struts is probably a smart investment. You can get by with a 7/8 02 sensor socket, but you will need to purchase a 22mm special socket that has a cut out. Or just buy both 21 and 22mm special cut out sockets. The DIYer should do their research. There are plenty of videos and BMW Enthusiast blogs etc with pictures etc. This a 2 person job with at least one person who is good with their hands.
