UPDATE: 330xi
Just installed summer tires & inspected the M3 shocks....
Dry, no leaks as far as the eye could see

BUT............
Now my 325xiT has leaky Bilstein HD
Not even on the car for 6 months!!
This car is NOT lowered.

Can I Put M3 shocks in to replace the HD?

Kubica - if I remember, you swapped HD for M3 on a sedan, is it lowered and how did that work out?
Thanks

I didnt love the m3 rears with stock springs in. I had some see-sawing getting on/off the gas/brakes. Not much but I didn't like it. They do seem softer than the HDs. I think the xi rear bilsteins over dampen the car, which possibly causes the to fail prematurely on rough roads.

I love the setup with eibach springs.

Didn't know you bought Eibach, must be amazing.
I would live to switch to that with Koni.

Just got my rear bilstein sports replaced with new ones from turner. They refused to give me the E36 M3 rears. Mechanic told me my dust boot was torn in the rear allowing sand and salt to get in and destroy the seals. Is that a valid reason? Crossing my fingers and hoping the new ones last me life of the car.

I'm not an expert, but I smell

I got E36M3 rears from Bilstein directly and they have been in for probably 3 months now and have not blown.

I recommend going directly to Bilstein.

Hate to break it to you, but... wasting your time. Within a few months you will go through this again. Call bilstein now & get your m3 shocks before those blow.
Denial & Crossing your fingers will nOt stop the leak lol
It's just a matter of time.
My 325xiT has the same problem, I knew they would leak, now they do less than 6 months in! M3 replacements coming soon.

There is light at the end of the tunnel friends, ***knock on wood*** the M3 rears seem to be holding up . . . but I guess only time will tell.

Yes. Luck or whatever, good for you
I have had 4 Bilstein Sports go bad, the first 2 lasted awhile, then the 2 replacements lasted about 2 months.

It makes me think we should be tracking WHEN they were bought.
Perhaps there was a change in seals or something at some point that is the cause of the failures. Oldest ones are good, newer bad... no idea!

It could also have to do with the ride height, H&R drop the most which likely puts even more stress on the shock than your Sport-Line springs.
Although, the shocks on my non dropped 325xiT that has Bilstein HD on brand new rear springs (both sold as OEM replacements) have leaked just as fast
Maybe Cali roads and temperatures are also much easier on them...

Today marks my 4th week on HD fronts, M3 rears, Rogue RSMs, and Eibach springs. The ride has softened a little and still turns very nicely. However I think it's settled a bit because the front has enough negative camber for me to be able to notice it when right next to the car looking from the rear doors. How much longer should I wait to get it re-aligned? Also, I'd rather just re-align it once more since there aren't many good alignment shops around here and a 4-wheel alignment runs about $110.

If you haven't done your front control arm bushings, and they are close to due, I would replace your CAB's before you have an alignment. Mine are just about due and I'm going to replace them before I have an alignment done. If your steering is stiff, doesn't return to center by itself or some other issue - I would look into alignment sooner than later. I have original BMW rears on my car, no leaks.

So Kubica are you running Blistein HD shocks upfront with M3 Blisteins in rear and Eibach Pro springs all around? I am thinking of this set up myself. Any other upgrades to suspension recommended with this set up?

For the street? That sounds good. Powerflex fcabs are a big upgrade and save a lot of cash in the long run. Bigger rear swaybar, powerflex rtabs, camber plates, strut bar, etc if you're into motorsports.

For the street, daily driver. So the HD's upfront and the "BMW Shock Absorber Rear (M3 E36) - Bilstein Sport 24-024532" in the rear, with Eibach Pro springs all around. YOu have this exact setup, right? How is the ride and handling?

And, I'm seeing the M3 rear Bilstein's on FCPeuro's website for $144 each - know of any less expensive sources?

^Yes, I'm using that exact setup right now. Handling is great and it's not too rough on bad roads. Check bavauto, turner, etc.

I, too, have that exact setup. Roads here are bad and it's not a chore nor pain to drive. It's stiffer so you feel more bumps, but coming from old OE suspension it will still feel better because the shocks are actually damping correctly.

Bumpy? Yes.
Rough? No.

Are you guys that are putting the E36 M3 shocks in the rear changing anything else in the process back there, other than the RSM's? Like spring pads, bump stops, etc or just going with stock for those parts?

Can't wait, getting excited to get these on and hopefully get a little lower stance with a more aggressive look.
