Rear M3 bushes

[trazy]

Hi guys

After getting rid of the runflats I've lost a little bit of connection to the road, so I'm planning for the rear bushes, after some reading I saw that you guys only change 4 of them but it seems that there are 3 others that are specific to M3:

I'm talking about the parts 9 and 12, my other concern is the compatibility with the other non-M parts that constitute you car, I mean they sure fit but the chassis hasn't been designed for them so something could go wrong ? I'm no mechanic, hell I can't even do my oil but I'm a bit skeptical

I have an E87 123d with sport suspension

I think the reason why everyone only does the four rear bushings are those are the ones that control or link the suspension to the chassis.

The three bushings you are referring to (#9 & #12) are to locate (hold) the diff in place. So you would only notice them on hard aceel or acell hop on take off.

IF you have the time and money... I would say go for all the M3 bits. Why not right>?

Good Luck

You lost connection? What did you replace the runflats with? Tasty strawberry fruit rollups?

As Dackelone said, 9 & 12 are just the diff bushings. The suspension bushings are the important ones. The M3 has a different diff, so you would have to make sure the M3 diff bushings would fit the 1 series diff first.

I believe the M3 shares two diff bushings with the 1 and 3-series, the other one(s) is different. If I remember correctly, one of them is actually softer on the M3, probably becuase the lack of torque it needs to control.

Mine has actually more torque than the M3, so I'll be looking into that thanks for the infos

One thing no one has mentioned are the bushing that hold the back part of the trans in position. On my e36... pppl would order 320i bushings for better "hard/quick shifting feel".

I wonder IF the M3 uses different bushings for that saddle that the back part of the 6MT sits on. A/T's must also have this saddle mount.

The E82/9X manual transmission car don't seem to suffer shifter selector rod misalignment issues like its older E36/46 brothers. The same transmission mounts for the E36/46 will fit on the E82/9x just fine.

What about the motor mounts? Are the M3 ones harder/stiffer? When our stock ones are wornout can we just purchase M3 motor mounts for an upgrade? I suspect the new 1M will have a boatload of goodies/M-parts that we can just plug in and play on our 135i's.

if you do this, please report back your findings, I don't want to half ass the rear bushings when i could do it right the first time. I wouldn't mind ridding the car of the axel tramp.... and rear end sloppyness. it just feels so wrong...
