Finally got round to fitting the B14 coilovers at the weekend.

Installed the shorter M Performance bumpstops on the rear and M4 LCAs up front.

Impressed with the results so far, still need to get the alignment done but definitely corners much flatter with sharper turn in. The rear feels a lot more planted over rough B roads where it struggled before.

The ride is slightly firmer but in no way too harsh.

Front - 25mm
Rear - 30mm

Hi, first post here. I had the Bilstein b12 pro kit on my 330d, I found it too stiff for our rough uk roads, I came across Birds autos and to cut a long story short had the B3 suspension system fitted, so much better it can handle the rough cornering so much better. The reason for joining this forum is I’m thinking of a baby 135i next year.

Just had the alignment checked and toe sorted.

I know the front camber is never exactly the same left and right but mine has more on the right side.

Is this still ok?

I wouldn't be happy personally.
Could be that the corner weights are out and the car is leaning (to the right) possibly due to being ballasted on the driver's side only during alignment.

That or some suspension member or subframe has been distorted.

To be fair the garage that did the alignment weren’t the best but the new hunter they were using gives them a step by step guide on how to setup and adjust.

Suspension install was done by a friend mechanic with me giving him a hand. We followed a decent diy from 2addicts and everything went fine.

Looking at some of the other guys alignments it doesn’t look too bad at 20 minutes difference on the camber. I’ve seen Marcos is 18 minutes apart.
