Rear Suspension Refresh

I have an '11 328i xdrive with bad rear bump stops. Was hoping to refresh my suspension while it is apart. The car has only 45k miles & the suspension is stock, non-m sport.

From FCP Euro, I see the Sachs shocks among others. Which shock do you reccomendation on the rear if I am not touching the front suspension?

I did see the Monroe (thread) & powerflex option on FCP. Should I go with either of these if the front stays stock?

They also have a full stock mounting kit - not sure what to order.

I used the OEM Sachs dampers on the rear of my E91 and have been happy. If you aren't touching the front, I would stay with stock stuff unless you're looking to really firm up the ride. You might be surprised with how much improvement you get just from replacing blown out stuff with new. I'm not familiar with the thread about the Monroe shocks. Do you have a link to it?

The full mounting kit is nice - I'd recommend doing shock mounts and the whole 9 yards while you're in there. Why cheap out and have to come back later?

Dang! That looks like a neat option, I have the same slight bounciness in the rear even after adding subframe insert bushings. Might have to give those a shot!

I recently replaced the B4 shocks, lower mounts, bump stops and boots on my E92, I didn't realize that the shocks were in such bad shape. I didn't want to lower it and the ride is comfortable despite the terrible local roads.

I like the Monroe top mounts.

I also prefer to support FCP over Mr. Bezos, but the Monroes are usually even cheaper over on Amazon.

I would do OE lower mounts, as well, though you probably don't have to. They're not made of the same soft rubber that the OE upper mounts are.

I agree, I try to avoid Bezos as much as possible especially for car parts.
