Hi All I know this has been mumbled around the forum a bit, but here is my progress for anbody who is interested So far I have bought a chunk of aluminium from these chaps and have drawn up some bushes using my shakey CAD skills. I have sent my request off to 4 machiners, and so far have had quotes of: 1. £120+VAT & Materials 2. £60+VAT & Materials. The Metal its self was £25+VAT and £14.50 delivery, but the Metal Fast crew where very helpful and it came next day. I think I will test run the bushes - hoping I got all the dimensions correct etc and see what the final costs are like and maybe if there's interest do a GB. If anybody has faith in my CAD drawing then I'm more than happy to Email it to you for your own fettling - PM me. So I guess best estimate so far is about £100 without postage, which is quite alot, so fingers crossed it will be worth it Alastair

I'm still interested dude. If you get some made, i know someone who can probably replicate for cheaper?

Wonder if its possible to produce some rear bushes using alloy and polyurathane to absorb a little more vibration ?
Nowt wrong with that,would be ideal

This has been quiet for ages, so a quick update... After getting some project work out of the way and making enough time to go to the machinest, The bushes have been made up and I'm collecting on monday. MattB is going to guinea pig them and if all goes OK, maybe we can think about a GB, if there is any interest....? So far the total cost has been aroundabout £100-110 Will post up some pics when I get ahold of them Alastair

I'll be interested too depending on how hard they are to fit and Matts write up after fitting. Good effort so far though. Mark

Im with Stan on this, its a cause of concern for the future.
Wonder if its possible to produce some rear bushes using alloy and polyurathane to absorb a little more vibration ? Would it not be better to go for poly ones? I'm up for either option - they're going to get done with the rear arms soon....

Poly isnt exactly that much more flexible.

Hmmm. Could the solid mounts be used as a mould for poly?

you cant use PU on the rear, there's not straight forward way of incorporating that into the design. Listen until you actually look at the rear bushes enough with the random comments about PU. You have to have a clamp design with the bolt through the middle, the std bush achieves that with some seriously well bonded centre to a rubber bush which is then bonded to an outer section. Under the middle section is a spot welded cover.

The poly bushes wouldn't be moulded (at least not for a run of this volume)
Much easier to get them turned on a lathe If you wanted poly, could you not buy a bar as the aluminium and turn them in the same way?

For anybody who is interested... Tah - Dah ! Now being posted to our in-house Guinea Pig Alastair Alastair, is the depth of the stepped section (parallel to the bolt axis) equal or less that the lip height on the sub frame - if its greater then the frame could move up and down in that space. if you turned the same thing from PU the bolt would pull through it and the lip on the frame would cut the PU in seconds.

Alastair, is the depth of the stepped section (parallel to the bolt axis) equal or less that the lip height on the sub frame - if its greater then the frame could move up and down in that space.Rich It should be the same so the subframe should be solid. I did wonder if you could make the bushes thinner to lower the back end slightly but I think that would have ended in the subframe not sitting correctly so left at standard thickness. if you turned the same thing from PU the bolt would pull through it and the lip on the frame would cut the PU in seconds. Rich
Thought that may be the case

Yes you could lower it, I may do this to mine as I made them too thick, the only issue you get is the hole in the chassis rail for the top damper bolt becomes obscured if the dimension changes. But to get round that for the occasional damper change I remove the top cap and raise it up on the bolt, of course it would be the other way round for a lower (thinner) top section.

......just have the rear 2 bushes changed, as these are the ones that begin to rot. I had Barbz do the horrible task of this for me & he siad it was a real sod to do. My bushes were solid alu' with no lady-smady damping rubbish / PU sleeves. I can honestly say that I cannot notice any difference in ride quality, except the rear just feels somewhat more planted ( in addition to the Eibach rear arb ). Taz

I think that settles it then - I'm interested in the solid variety.
