Anybody ever install these? How difficult is the installation? what are the steps? how much difference does it make in performace? right now i want to stiffen up the rear more as it is overly stiff in the front. Hoping this will do the trick as my rubber bushings are beyond shot.

As far as I know you need a press as they are a bit*h to get in and out, I'm pretty sure you can also buy a replacement arm with them istalled already, you can in some cases (Front's I know you can but rears unsure???) you can get away with a vice and a few larger size socket's........ |

I believe the urethane bushings for the rear trailing arms are two pieces, one piece goes into each side. Depends on manufacturer though and I'm not really up on it so I could be totally wrong. Getting the old ones out is still a bitch though. |

those are what i bought,(yet to arrive) and yea they come in two pieces, does that make them easier to install?
How many hours shop time would a mechanic take for this? Does splitting them into two make it easier?
the ones in there right now are beyond shot, but yea if you normaly have to press them in, i will not look forward to taking them out

I fitted mine no problems.
I slid an m10 threaded bar through one side, before it went through the other mount I slid on 2 large penny washers 2 lengths of 1/2" tube and 2 nuts. I then wound the nuts down the threaded bar until the bar was through the second bush. I then wound the nuts in different directions until one mount was pushed out.
I then wound the nuts back together until I could fit a plate with a small hole in the middle over the aperture for the removed bush.
I then wound the nuts out again until the second bush fell out.
To fit the new bushes I just reversed the process putting the nuts on the outside and pulling the bushes inward.
As far as performance goes It is very hard for me to judge because at the same time I fitted my Leda adjustable shochs and lowering springs.
I would say that it does feel tighter put wether this is the suspension or the bushes I cant say. |

I think he is referring to m10 as the diameter of the threaded bar (or also a long bolt?). You'll find out when you go to a local Home Depot/Lowes or what have you. |

I've got some Paul Gray "grunt" bushings in my e28 and they do make a big difference. The only downside is that they squeak like crazy if they're not kept clean and lubed.
Mine goes to the local shop at least once a year to have them taken out, cleaned, lubed and reinstalled. They work cheap, otherwise I'd do it myself 
I've spoken with several others experiencing the same issues but like me, they agree the benefits outweigh the negatives. |

hmmm .... I don't think I can afford (time wise) to have the rear removed and lubed on a yearly basis. |

a good silicone based lube is all you need. usually come with bushes if you buy them new. |

This is what I did:
Sorry for the dodgy drawing but I did it quick in my dinner time.
My bush's came with silicon grease.
They pushed out really easy and sliped back in no probs. |

Any silicone lube will work.
My driveway is 1/3 of a mile long, gravel and gets dusty during the summer. If I didn't drive on dirt roads as much as I do, I doubt the bushings would get quite as dirty.

I don't suppose u can crawl underneath your car and spray some sort of lubricant instead of removing the whole trailing arm? |

no because you need to lube between contact surfaces. If you dont use lube, it will tear out the bush. If you use the wrong type, it will break down the rubber and render it useless too.
Silicone based lubricant is about one of the only things that doesnt have a negative effect on rubber/urethane. |
