They look good but I have already bought mine from Flow-Flex they are two pieces with crush tube like the top section of your ones ie flat that is why I was thinking of the large washer underneath because they don't dish in so I think that would be okay what do others think?.
Regards Mick.

That's what I was going to do with mine. Use the floflex bush and tube, and make a large 'washer' the same diameter as the bush, around 5mm thk. You could use a standard washer (as long as the washer is bigger than the crush tube) but I would like the look of a chunky one!

I have ordered my gbs diff mounting kit which is coming in at a whopping £150, but with this bracket kit, you cut the arms off the diff completely. I don't know how this works exactly, because when I went on my tour of gbs, there was no diffs available to look at, which was a bit of a shame really. But, if your bushing at £35 pounds each ( if my conversion rate is right ? ) , will be a much better deal. I know you have to include shipping, but still would work out a lot cheaper. :D

I couldnt find any information on anyone having a breakage that wasnt in a accident. The only negative information was with the use of aluminum bushings and the excessive noise. With the poly units being a nice compramise between the stock rubber and the aluminum set. As for cost, yes about £35 plus another $30 for the shipping. Can you get access to the US version of amazon.com, shipping might be less going through them.

Are these designed to be used with the mounts that come on the MX5? The ones that sit under the diff arms?

No the replace those with those 2 big poly pieces and just reuse the big washers.

75mm x 5mm disc on eBay 2 off for around £5 and drill hole in centre is what I have decided to do with mine

So are guys just using pressure to hold the bushing in then? Instead of something that extends beyond the bushing to catch the bottom side of the carrier.

I'm using a design alteration of the original ie by NTS/Saturn which has alterations to the diff cage.
Two plates 5mm thick one on each side bolt through from top diff mounted underneath then large 75mm x 5mm disc and nut, Flow-Flex bushings in diff carrier these are flat both top and bottom of diff carrier not dished like the ones you are using so yes the bushes are compressed between the top plate and the disc there is a crush tube through the centre of the bushes so they will only tighten up so far.
Regards Mick.

cant say im a great fan of the mx5 diff design and the way works in 7 kits.

i have looked at both the mx5 redesigns and if it was me i would be going down the talon/voudu one if i had to build one of the two.
i dont like the way the other one is designed

stress is under estamated in diff areas and even some of the pro's got it worng
