Why E34 rearends are loose

[steve0suprem0]

Also, check out this tutorial about adding a plate underneath the bushing to stiffen things up:

correct me if i'm wrong, but this is what we're (or, everyone else, rather. while i eavesdrop) talking about right?

also, great thread, lotsa info. and another thing, you're absolutely right about the profanity. unfortunately, i'm one of those guilty, and there's no excuse for it. other than i'm usually pretty upset when i do it. which is probably worse.

Did the same thing myself! The one thing that made more difference than anything else was bruno`s delrin inserts.By the way, the best handling cars on the planet do not have sway bars at all as they are a compromise to support a bendy shell, which the E34 does not have. Try upping the spring rate by 30% and dropping the sway bars altogether,just dissconnect at one end to try.

@repenttokyo:

Bruno's subframe inserts. I figure they can only help. I may even try to engineer something up myself to really stiffen them up. I've read about people pouring urethane in the voids in the OE subframe bushings and would probably recommend that to anyone intent on changing them out. I may try to figure out how to pour that stuff in mine while the bushings are in the car. After this whole ordeal, I suppose I'd recommend upgrading your subframe bushings if you're trying to stiffen up your E34 rearend. The OE trailing arm bushings, diff mounting bushings and subframe rear mount all appear to be well engineered and long lasting. In my opinion, the subframe bushings are just poorly designed and contribute the majority of the looseness of the E34 rearend.

these are the same things as the bmwe34.net link you posted, right? or is that something else entirely? not trying to be rude or anything, just double checking my own understanding.

Not sure how much this helps, mostly due to the fact I don't have experience myself, but I've heard from several people that bruno's inserts make a world of difference and is one of the first mods you should do as far as price is concerned.

VF Engineering - I assume that's what VFE is... do they make a kit for the e34 or are you customizing from one for an e36?
