For a direct comparison it would be pretty quick to remove them again...

This? any vibrations, noise etc? i went for M3 since i wanted less wiggle but no significant increase in noise/vibrations.

Nope, just the inserts, not the full replacements

The inserts are part number KDT918

I've read most of the threads here (at least twice) and many different people have many different opinions.

Exhaust sound likes and dislikes are all pretty subjective, so whatever floats your boat.

PS - personally, never liked the stock black tips, but it seems that a lot of people like them, so what do I know. lol
Yeah, from what I've gathered reading zillions of threads and watching videos, the sound is more or less the same, so it's just a matter of how loud one wants vs. the amount of drone.

Hmm... wonder if this is the answer? I only have ~40k on my car so maybe my bushings aren't "old & squishy" enough to feel more positive results with the inserts.

Not according to BAN_M2C in his post I linked to. Sound is louder with the y-pipe. And like I said many times, no drone to speak of for me. It is easily controlled.

We're mostly saying the same thing.

Stock exhaust: loud -> Stock resonator with PE muffler: louder -> Full PE: loudest

The question is drone, and then it's just a matter of sensitivity and what one wants. For every person that says it's no big deal, there are others who say it's too much. So, for those wanting a middle ground w/ a louder sound, but w/o much drone potential, the stock resonator + PE muffler should be mentioned.

That's my theory. Also thinking the inserts will keep the stock bushings from getting mushy as quickly

duder13, do what you think is best for you.

I've had my exhaust (PE with y-pipe) since 2011 and am perfectly happy with it.

Cheers!

I am seriously considering the bushings now....

I will give them a call tomorrow and ask, if they do same day shipping (i get the bushings Wednesday) i will go for it and return the M3 ones.

Installation looks much easier than the M3 ones, especially the fronts.

I know. Luckily its starting like a champ now. One of my 16 year old boys "borrowed" it while I was in NY, and must have left something on.
Classic BMW Service recommended replacing it 2.5 years ago. Said it wouldn't last.

So you recommend solid rear bushings over M3 ones and whiteline?

It seems like those who favor the inserts and had a good experience with them have higher mileage cars, some of which are 128i's. With this in mind, it seems like the bushing inserts are taking up some of the slack that a worn suspension begins to develop over time, thus providing an improvement in road feel from the rear end.

As I said a few posts ago, and a handful of other times on this forum, bushing inserts are snake oil, and a shortcut to doing something the right way.

The factory subframe bushings are designed to work in conjunction with rock hard run flat tires, and to work with the rest of the suspension to absorb road imperfections, bumps and other feedback. Switching to conventional tires reveals the inherent weakness in the suspension, which drives many to upgrade their bushings, arms, springs and dampers. When I tried the bushings myself on my first 135i, my mechanic refused to install them for obvious reasons.

In my opinion, if you want to improve the suspension on a 1 Series, buy either M3 bushings or go with a solid or poly solution to really stiffen things up. Do this in combination with improved dampers, like Bilsteins, along with front camber plates and both ride comfort, compliance and handling will be greatly improved.

Im running non RFT summer and winter tires, KW v3 coil overs, ST 28 mm front bar with Meyle HD end links.

Rear end i was planning on M3 bushings, 15 mm sway bar w/Meyle HD end links (LSD is planned in January). But now i am not sure if i should stick with OE M3 ones, Poly (Whiteline) or Solid (only 1 company in Germany supplies them https://www.parts33.com/product/irp-...tarr-aluminium)

M3 front upper and lower arms are also going to be installed, probably this week if the alignment shop is free Friday, only concern with Poly/Solid is NVB, since the diff is getting replaced, M3 diff bushings are also planned. Car is 100% road driven in Winter, and 80% road and 20% track in Summer.

I have the Whiteline inserts. They work for me, but if I had it to do over again I'd probable get the 2 piece poly units. But I don't know if the add any NVH.

Man, those old spark plugs were junk. The car pulls SOOO hard now. 3rd gear is an absolute hoot, and 1st and 2nd now have a little bit of traction issues. The car has never gotten to highway speeds so violently before, it's amazing.

Spark plugs. Who knew?

Anyways, I ordered a power steering flush/refill kit from FCP (Pentosin CHF-11S and a new reservoir). The fluid in there now is a cloudy, almost opaque green (it's supposed to be translucent). The pump is also a little whiny for my liking, but the E90 threads I've read have said that a flush fixed their whining issues.

I'm in love with the car again...

The Whiteline 2-piece bushings are fine. The main benefit over M3 bushings is the ease of install. They are 1/2 the height of the M3 bushings so you donít have to mess with levering the subframe as much, and they donít need to be pressed in. You can push each one in with 1 thumb. Once the old bushings are out, it is 5 minutes per corner to get the new ones in. There is no additional NVH that I noticed.

You are overthinking this. They are bushings - put them in and go drive the car.
