i dont know about the front but in the rear on my e36 m3 I had the same issue. Turned out to be worn out trailing arm bushings gave my rear supsension too much vertical travel

If you are experiencing a front/rear noise visit this thread I created that shows you how to fix http://forum.e46fanatics.com/showthr...204&highlight=

If you are experiencing height issues in the front PLEASE make sure you have the coilover seated in the "hub" correctly. If not seated correctly it will result in a like factory height. The hub can be a real PITA to get apart.

If you are experiencing height issues in the rear please provide me the part numbers from your perch and spring. Also fill this out http://www.s45inc.com/files/Coilover-Measurements.pdf

That's my first guess..

The front is definitely installed correctly and it did drop a significant amount from stock. It is as low as it was meant to be based on other pics. The rear is just much lower. If I adjust it to full drop I could hide the entire tire and just have rim showing. I'll fill out the measurement form and get it to Kris to see if it is normal or not.

The fronts are seated right. I rechecked everything when I did the FSMs last week.
Strut nut torqued with the tool with allen wrench to 37lbs.
Fronts almost all the way low, one thread remaining on the perch.
Rears almost all the way up, one thread remaining on the perch.
Still getting that creaking noise and grinding when I go over the bumps.
Nothing touching anywhere.


Will check the part numbers and heights this weekend.

Did you reuse the stock washer on top of the coil over? Did you torque the pinch bolt to 60lbs? Did you install new top mounts? Did you torque the top mounts to 25lbs?

Just some things to check. Mine are completely noise free, just have the lower in the back issue.

I'll finally have all the parts I need tomorrow. Only waiting on the rear shock mounts and reinforcement plates at this point. Got a few extras I didn't need (like new rear lower spring pads, since it's the uppers that get used instead, etc) but can't hurt to have on hand I guess. I did get new washers and everything, pretty much new hardware for everything, so I'm going to try to loosely (not torqued yet) assemble the struts and mounts tomorrow morning, and assuming FedEx comes when they did today (bright and effin early), I'll get the rears together too. Then it's just pull the old out, put the new in on Sunday. I'd do it in the driveway, but I don't have a torque wrench, and from everything I've seen so far, things need to be pretty darn close to avoid clunks and whatnot. And I don't want to clunk! I'll try to get some pictures along the way though, for two reasons: If I'm wrong, the pictures will help me figure out what to correct, and if I do it RIGHT, I'll have pictures of it so people can see lol. Tomorrow is way too far away...

Yes to all the questions.
I did the whole process twice. Once during the installation and once last week when I changed the front mounts.
The noise I am getting is from the driver side front strut area.

I may have missed it previously, but it's not something else in the suspension that just seems to have woken up noisy after the install? sway bar bushings, CABs, end links or anything else that might have loosened up? Just trying to think of what else might be there that could cause any noises.

FCABs and RTABs are new.
The only thing I can think of right now is the endlinks. I used the new ones that came with the coil overs and re checked their tightness last week. All the joints and nuts are tightened to the spec.
The issue is the sound only comes when there is load on the suspension; like turning the wheels or going over the bumps.
If I were able to recreate the noise while on the lift, I would be able to point out where the issue might be.
Well, going to check everything again. Its getting really irritating having to change things one at a time and the issue not getting resolved.

Try checking the sway bar bushings and mounts also. I have run across a couple cars that have actually cracked the mounts right off the frame rail, granted they were running huge bars but its worth a look.

I had a creaking/clunking in the front driver side as well, the top but on the coil was not right enough. I couldn't get a torque wrench on it so I just got it good and tight and the noise went away.

Only other think I can think of is did you get reinforcement plates for the mounts? Also is your wheel far enough away from the shock? I didn't use spacers and I am really close, but I remember others saying they were rubbing a bit on bumps.

I didnt use the re-inforcement plates for the front mounts. I am going to install strut bar soon. So i figured i didnt need the plates. No deformation of strut towers on mine. So i am good on that. I did get the strut nut torqued both the times.
I have 10mm ecs spacers up front and 15mm in the rear. So its not rubbing.
Just not able to see what is causing the noise.
I am going to dismantle everything put it together this weekend. Ordering the sway bar bushings now. Sucks to keep on adding parts one at a time and still issue not getting fixed.

Assuming the weather holds off in the morning, going to be putting the front end together on mine tomorrow. Turns out my step-brother is a bum, and planned to do other stuff on Sunday instead of letting me toy in the garage. So, I've put everything together, had him torque the top nuts onto the mounts for me (since he had the tools for it, I took them up and made him go do them on his lunch break lol). So tomorrow is install day for me. If all goes well, it'll be the front end, plus CABs while I'm under there. If time left, I'll do my fuel filter and oil change, but I mainly want the front buttoned up. I'll probably also adjust the rears down a little more, now that they've had time to settle in. Will definitely take some pictures when I get it done!
