e36 M3 control arm bushings in Xi

whos actually done this...
how long have they been in?

any input would be great! this would be a fantastic alternative over stock and powerflex bushings. not too pleased with 2 piece powerflex that is currently installed in my car

As long as the diameters are the same, they should work fine. My 2002 330Xi has 66-mm diameter bushings, but I'm not sure what size the M3 bushings are.

I'm confused...

ixtoxi, you own a 2002 330xi and say that your CA bushings are 66mm.

e36-2.0, you also own a 2002 330xi, and say that you have 60 mm bushings.

How that can be possible. I checked in ETK, and they have the same part # for all 325, 330 xi, for all years.

I'm more confused becaused I just ordered a set of Powerflex CA bushings for my 2002 325xiT, and, even if the bushings were specific to the xi, they don't fit. My carrier is 60mm and the bushing is 66mm.

Does someone has an explanation on this, or experienced the same problem?

Thanks.

Has anyone here tried the e36 fcabs in an xi?

My mechanic says the bushings will fit in the carriers, however the center holes are different diameters.

Did you install them personally?

You had the powerflex one-piece bushings previously, right?

My mechanic, who works at Turner, keeps telling me they won't work, since the thickness of the control-arm is different.

e36-2.0- where did you figure out this was a good mod/upgrade? So far you are the only one I know of that has done this.

Thanks

i had them for about a year now and so far no problems. installed by my mechanic but i do think i could have done it myself if they were pressed in the carriers already. i did however just get new suspension in a few weeks ago and now feel a shake in my steering. but i dont suspect the CAB bushings are the culprit though but rather balljoints are worn again

and yes i did try powerflex bushings. they were fantastic at first but i lost confidence in them completely when the 2 piece bushing design separated and did not sit properly inside the other.

Thanks. I bet your ball joints are fine- proabably need new bushings again.

I'm not trying to be a d!ck, but fom what I heard, if the powerflex weren't installed at exactly the right depth, they could separate.

Crappy OEM that last 20kmiles VS. aftermarket that may separate.

Hmmmmmmm . . . . .

I put the powerflex in myself about 10,000 miles ago, no problems so far. My car used the 60mm bushings. I bought them from bimmerworld.com, Jay there told me all XI's use the 60mm E36 bushing (and I also measured with a caliper before I ordered). I did ask him why there was another powerflex bushing (part no PFF5-4601Xi, 66mm, instead of the 60m PFF5-301) but he never responded... I found on the internet somewhere that it was for cars with the BMW carrier part number 31126757623 but I can't find a reference to that part no on realoem, but they're for sale on turnermotorsport, but say they don't fit the XI.

So at the end of the day, I don't know if XI's truly did come with 66mm bushings, and I'd really like someone to prove me wrong. Once that happens, we can attempt to determine what years/options they came with.

Update on my install:
Since the Powerflex are 66mm and my carriers are 60mm, I had a friend machinist who opened the bracket to 66mm, and I welded a metal strip on the OD of the bracket to reinforce it. They are on the car for 1 year now (22000km) and they work fine.
For those who have the bushing that separate, you could just thighten a clamp on the control arm to act as a stopper. I put one on mine just in case and they never moved from the installed position.

I think he meant the inner and outer portions of the fcab separate, not the control arm from the bushing.

Can you comment about handling?

It sounds like you have RWD bushings installed on your car now?

Yes, that's what I mean, to stop the inner part from sliding on the CA pin and forward. I put the clamp forward of the purple piece.

Handling is better. With my OEM bushings, when I was braking, especially on bad roads, the car had a tendancy to shift left or right (especially with my directionnal tires) Now it brakes straight.

May be they are RWD, I don't know. But when I compared them with my OEM ones, both sets had the hole centered, so the caster shouldn't be affected.
I had the car aligned a bit later after my sport springs install, and everything was within specs.
