What aftermarket bushings are best to start with?

[no6thgear]

I'm installing koni yellows and super sports soon. What are the best things to change / mod "while im in there"

I'm thinking front sway bar...but are there any bushings that I should do where part of the labor is done during the strut install?

Thanks

I installed aftermarket rear subframe bushings (whiteline), rear M3 toe link conversion, and KW coilover installation at the same time. When doing them together, there is some time savings.

I would seriously consider doing rear subframe bushing inserts or replacing the rear subframe bushings while you are in there. They have a significant impact on the cars handling. You know that first gear wiggle the car does on hard acceleration or over a dip in the road while cornering at speed? The soft rear subframe bushing are the cause of those and they are eliminated with stiffer bushings. (this was the first thing that I wanted to fix when I bought by 135)

thats exactly the opinion I was looking for. And I thought bad struts may have been causing that issue too...didn't know it was related to those bushings.

glad to help. here is the link I read which includes the steps for a diy install. Some shops charge up to 8-10 hours to install subframe bushings but alot of fourm members have done it as a diy in 3-4 hrs.

I'm seeing 2 piece sub frame bushings....and 1 piece ones. Are the 2 piece "inserts" just easier to install than the "bushing" or something?

Rear Shock Mount: Anyone use this...big difference?

inserts look like they have lil legs on them. the full bushings are 2 halves.

inserts will be easier and you won't need to press anything out but they won't be as firm since it's just filling the gaps of empty space around rubber.

I did the inserts because I wanted to try something on the cheap and didn't want to press anything out. I have the worse of luck especially when i comes to suspension.

i haven't heard anybody posting about those shock mounts. i can say that the rear shocks would be the easiest part of working on the suspension.

I did the full rear subframe bushings (replaced E82 soft bushings with stiffer one-piece E92/M3 bushings) as a DIY. Major PITA in pressing old ones out and new ones in, but the results are outstanding, even on stock sport suspension. Rear of car is now planted and very predictable. Should be one everybody's top list who want tighter handling.

Inserts are the easiest and fill the voids on stock soft bushings. I think most will say that they are happy with this, but rare are those that have experienced inserts, two-piece bushings, and one-piece bushings and can objectively compare the three of them.

Two piece bushings require more effort than inserts since the OE's bushings have to be pressed out. Might as well spend another $100-$150 and get the full E92/bushings or solid one-piece aftermarket bushings in there ...

Sorry for the thread jack, but...... Does anyone know what the torque specs would be for front/rear bushing bolts?? Thanks

How did you do the front subframe bushings? My mechanic is saying they'll go in from the top, but that's backwards given the lip on the bushing isn't it? Need some insights/opinion here...or pics?

"...to replace the front bushings on the subframe. Manipulate your jacks to give you the maximum amount of clearance on top of the bushing you are working on. The removal process really is the same as for the rear bushings. Be sure to use the tool as directed by the supplier. Again, the flange is on the bottom, so the bushing should exit to the bottom. However, when installing the front M3 bushing, the flange is on the opposite side. The M3 bushing must be installed from the top!"

Thanks man...I remember seeing that post but that helps a lot.
