Rear diff hanger reinforcements

[Yaninnya]

no point as even if you do use the e36 diff cover it can still pull away as the beam is the ONLY rear Stabilsing bar at the rear best thi would to be develop some anti tramp device from hard launches

I don't really agree, also the beam can be reinforced aswell with out much bother, i.e weld a thicker plate where it bolts, same as james3320 has done with his m50 turbo.

Any how the proof is in the pudding and i can't find any links of e36 carries being distroyed

Logic is the proof. The diff is solid mounted to the beam so if beam diff mounts will not twist the diff will not rip of the rear mount. It is so simple that I don't understand why so many people is reinforcing rear mount. In E36 you can't find any carriers being destroyed only because it is mounted to the subframe on the back as well. And is twisting with the whole subframe. Check the problems with subframe bushes in E36. That is because of diff.

Hi guys, i have ripped my diff off, not a very pleasant thing, i think i need some of those drive shafts also, any info on them?? also i have actually installed a M535 diff on my car, ill try getting some picks loaded up soon, not a straight forward job, also,

Does anybody actually know how much power these diffs can hold???

[g57yle]

sorry, my bad i didnt read the posts ubove properly, thats great power holding, it should be just right, but those twisting half shafts may be a good thing for me as i twisted my prop and drive shaft splines aswell!

[oldroydsr4]

How much power are you running now?

It must be a real beast, im doing the rear diff hanger to support 350bhp, so the gearbox etc should be ok.

[g57yle]

will be running around 700+

Have you considered using ZMRoadster/Coupé rear arms? They give you much larger brakes and slightly larger diameter half shafts and diff output flanges. A bit stronger.

any pics of your diff mate as i need to do mine!!
an il find the half shafts for ya.

[Colonel Sanders]

think these are the ones you will need as they fit the e28 diff, but not sure on this so best to email andreas and speak to him.

works out around £350.

I am now using Z3M drive shafts along with the rest of the rear axle just with E28 M535 LSD and the drive shafts bolt straight to it, so ill need a pair of Z3M shafts

But the question is: how much torque can these new shafts hold???

Oh and here are a few pictures of the rear to give you an idea of how i got the diff mounted.

Its a E28 M535 diff with an E46 rear diff cover that unbeleivebly bolted straight on!

I removed the floor skin where the diff sits under and replaced it with 6mm thick iron x2 side by side, then used 2 L bends ontop making 2 triangles and got a bit carried away and used a pole with a 6 mm wall which i welded ontop of the 2 triangles and you can see the rest!, you can probably hang a house off that!

[oldroydsr4]

Does the m535i diff bolt straight on to the rear beam, so the only mods are the back plate or are mods required on the beam to.

[g57yle]

correct, its bolts straight on to the subframe, so it just needs the rear section done

[Colonel Sanders]

shafts will hold well over 1000hp.
does anyone know if the m535 diff halfshafts will bolt to standard e30 rear end?
and would it bolt to the standard e30 prop?

[g57yle]

it will bolt to the standard prop but i cant say about the rest cos i dont actualy own a e30 rear end

[oldroydsr4]

The only problem i can see is that the ratio of the m535i is 3.07 ,which equates to a top speed of 194mph.

I think this would be far too long for most cars

[g57yle]

yes normally, but in mine with my 6 speed box and my 19" wheels it equates to around 240-250 if i calculated correctly, but im not sure ratio diff i used to calculate that now, either 3.07 or 2.81? Hmmmmm

yes, for non turbo cars or 5 speeds also, i had a 3.25 from the z3 m before and i still needed a longer first gear, ideally i would like a 2.81

i still have the z3 m diff if anybody wants it, but ill hang onto it till i know this diff is ok

[g57yle]

Oh and how are we supposed to transfer this power through our donuts???

as you can see in the second picture it actually twisted the flange on the prob so the bolts were looking twisted that are still on the prop

This one was 2 weeks old, i then used a E36 one with a larger bore, but im currently not using one at all

[g57yle]

Oh and guys, the E28 diff is actually longer, and wont really fit unless you cut out some of your support bar as i did

[oldroydsr4]

by the looks of your power train i think its time for custom prop etc.

www.torqline.com

they do the props for 1000bhp + skylines

I already am Jai, took me over a year to find them!

Yess, good idea,

I just sent them a request via their site

Thanks

Wonder if it would be possible to strap between the bolts with say some 1mm thick stainless bitties which would be loaded in tension when the power's on.

If you used say 9 of them (three sets of three) it should still be pretty flexible I reckon.
