I'm really thinking of doing this. However, I found that Powerflex sell inserts that fill in the gaps in the OE bushings.
I had read this in a post somewhere but I can't find it now. Has anyone had any experience or heard of using these. The advantage is simply from an installation perspective. Of course the vendor info says that it works great. Apparently the real issue with the OEM is that the are hollow. |

i cant wait for my bushings to get here! I ordered through dan@united, his shipping was 100 bucks cheaper to my APO address than HPA's.
I will probably do a suspension/brake install all at once, since the system needs to be bled anyway.I was planning on dropping the entire rear axle/subframe/suspension as one unit. I think that would be the easiest way to do it, and wouldn't require an alignment, because none of the suspension components would be removed from the subframe. Im going to do my front suspension at the same time, so i will get an alignment regardless, but to people doing this as a solo mod, i think that method would be a good way to save a few bucks, not having to re-align it. |

How much did you guys pay for your Powerflex inserts? The last time I looked at them on the web... they wanted over $460 for the rear axle set. For that kind of money I would rather have quality BMW M3 units. Which is why I went with the M3 ones. I agree with your stteering comment opvaulet the whole front end feels much more planted now and seems to work better. Like I have said in my OP these rear bushings really transform the way our cars drive! It is a MUST DO mod as far as I am concerned. I might be able to live w/o an LSD but I had to have these bushings. Especially now that I can feel how much they improved teh way my car drives! Dack |

Harold at HPA will rent out the tool, well worth renting, it can be done without them if you are McIver or some kind of boy genius, it's a snap with the right tools. Before and after is like day and night, well worth it as far as modifications go.

Here is where I found the info when I was looking to find out about them. Quote:
On the road, the difference is very apparent as the rear has no sloppy feeling whatsoever. Left to right transitions are very firm and planted and has a better solid feel. http://store.powerflexusa.com/bmw-e8...ngs-p1203.aspx This website does show an array of different bushing replacements for the whole suspension with teh most expensive ones at $459. The solid poly ones are about $259. If I had to do this again, I would probably go with the M3 bushings and have someone install them. Now don't get me wrong, the inserts are a great alternative for the DIY'er and not bad at all for the price. Once I have more time in the car since the Bavarian weather is "so Beautiful" during this time and I have to wait to get my license back I can give a better review. For now, that is my initial assesment, but will eventually go with the M3 bushes.

I'm visiting the dealer in the morning to get a quote for the M3 rear subframe bushings, the M3 bits up front, and the performance suspension so I can figure out where to order my parts. Other than tint and debadge, I've really never modded any of my cars, so I figure with this one, "it's now or never" and "go big (for me anyway) or go home".
Cheers, Bryan |

+1 on the M3 rear subframe bushings! I just had them installed, and the car feels sharper, tighter, along with everything Dack already mentioned. Definitely worth the money!

Dack,
After a year or so of having them, any signs of wear or any changes in handling? Still the same nice, planted, solid feeling?

What has impressed me most about changing these four rear axle bushings to the M3 parts... is how pronounced the change is to the FRONT axle. The car turns in better and responds to steering inputs better. The car tracks better, and it feels much more nimble than before. Changing these four rear bushings really have helped the sporty feeling of the entire car(suspension). Put simply it is a MUST HAVE mod. Also a note: for the 6MT guys(like me) upgrading to e46M3 rear trans saddle mounts is also a good upgrade. Its on my List for Spring time mods. Right now my car is sleeping for the winter though.

You can do all four bushings in about 5 minutes with a mapp gas torch and a flat socket. Drop cradle enough to place socket over locator, then jack up cradle until it is supported by the car. Apply mapp gas to sleeve. Car's weight acts as hydraulic press and bushing comes out like butter. Super simple, and you don't have to deal with wrenching on a removal tool.

I know this thread is a little aged, but I'm getting the bushings done this weekend. Mechanic said the same about the front subframe bushings, but he thinks he it might unsafe going through the top...any thoughts on this? I know the bushings have that lip to keep them in place...to a degree, so is that lip just pushed through until it pops out the other side or is the bushing installed backwards?
