I just installed Bruno's rear subframe inserts.

[Bimmer Nut Ed]

It was so easy. Took all of 10 minutes, max! I did not even lift the car, I just removed the 2 13mm bolts and the 22mm nut, inserted the insert, and re-install. Piece of cake. Now for the daughter’s car next, as soon as she get home!

I have not driven the car yet, and might not for a little while. With the weather like it is. It's Beemer Weather! Besides, the inside of my 5er is apart waiting for a sword right now! And it usually take me about a week of driving or so to detect any subtleties in handling. Anyway, maybe I'm a little skeptical, but I can't see it really changing the ride much, but I can see it preventing major movement in that bushing, therefore preventing early replacement of that bushing, and heck, maybe even preventing having to replace that rear subframe bushing at all. And that's good enough for me, I like it already. If I find any ride differences, I'll be sure to post.

Steering seemd quicker, wandering down a bit and cornered a bit flatter with less corrections needed during a corner. I do believe it reduced or even eliminated the need for new sub frame bushings. There may be a a tiny bit more harshness transmitted to the interior. Not sure. Overall, it is the cheapest quality upgrade I have done to my car. However, Mark's E.A.T. chip ranks way up there. FYI, I also installed Bruno's front suspension thrust arm inserts. They eliminated my 55-65 mph shimmy and made the car even more precise. Great products!

Next comes the rear suspension dog bones. I think they are "soft". It seems that as each component is replaced they suspension is much tighter.

I can't seem to find the thrust arm inserts anywhere on the Racing King website, or the BMWE34.net site. Bruno, we want more of your stuff. Thanks Bruno.

Also, are you saying there will be inserts for the dogbone bushings as well?

Thanks for the boost of confidence! I was worried that something was going to fall down on me when I put those inserts in.... but nothing! they were so easy.... I did have to buy a 22mm socket... but I'll probably use it again (dog bone boots are slightly torn)

Didn't even lift the car, just threw down a piece of cardboard in the drive way and went at it!

Haven't had a chance to test them yet, but I'll be out later this afternoon for a little drive

Sorry for being out of the loop a little... but what part are you guys talking about??!!!
It all sounds very interesting and I think I want some!!!

Ed...a question...did you use an impact on the 95 ft-lb 22mm nut(s) when removing the sub frame bushing plates? I need to remove mine and wonder if an impact would put too much stress on the large carriage bolt(s) up through the car's floor board which is restrained I believe with a knurled interference to the floor board....don't want to spin/strip out that interface.
Or did you just use a breaker bar on those bolts?
Other opinions?
Thanks,
George

I used an impact to remove and a torque wrench to install on those bolts. Probably not the greatest idea, but I had no problems.
