Filling rubber bushes.

Post Fri May 01, 2009 10:28 pm

Fitting some new subframe bushes which have nice big holes in them.. What could be used to fill the holes to stiffen them up a little?

Tigerseal does a good job on landrovers used off road from what I have been told.

We've been through a couple of tubes of Tigerseal - it's awesome stuff, sticks like sh*t to a blanket but remains flexible. Don't get it anywhere near the bodywork though

Fantastic stuff isn't it! A mate of mine makes car transporters and the stick fecking great sheets of metal on a vertical surface with it!

Dan If you don't have any joy, I think I have some at work if you need me to pick up a tube.

Well i'm not trying to stick the car to the side of any building.. The road would be handy though

Can't you get that liquid poly stuff?

Some bloke over the water did that and there's a guide for it somewhere...

Hang on!

doesnt somebody make (or made) plastic inserts that you push into the holes. was possibly a group buy and was possibly american.

Dont want to state the glaringly obvious, but shouldn't the bushes have the right sized holes in them?

Or am I being daft!

There are voids around the actual sleeved rubber bit. 2 smiley looking faces which you fill.

That explains it - I thought I was being daft.
Silicone is the thing then, I would say.

Someone on e30tech.com had some made up a few years ago; I can't find the thread but THIS is pretty much what was done.

Which bushes are we talking about gents? The ones that join the rear sub-frame to the body?

I turn my own on the lathe from a length of polyurethane round bar. You can also use Nylon, Vesconite or Tufnol depending on the hardness of the ride you want. I press all the bits back together with an hydraulic press. They are good for the track, but the stiffer and/or weaker the material you choose the quicker they wear out.

I also do the same with the front control arm bushes (just below the footwells) since I can't get the solid M3 bushes here.

Got the inserts here if someone wants to make me an offer?
