Hi Guys,
When recently working on someones car It occurred to me that whilst I know what the rear triangulation mount on a Cosworth does and how much movement it has as standard which ruins the rear geometry, many owners most likely don't have a clue.

It also came to mind that most owners probably think that it is in fact only a differential mount, and not a very important triangulation mount that aligns thr rear beam. (hence my carefully chosen topic name... lol)

So I got the chaps permission to use his car for a couple of videos and have made a couple of short Iphone videos as follows:


This one shows you exactly how much a standard one moves.

And this one shows how a decent one simply doesn't.

In the film I say now we will move the car, but of course i mean the diff, as the car is on the ramp above us and i am simply having James lift it up to show how much it moves under easy pressure. It will move more on the road for certain.

Here is a pic of the aftermarket ones next to the original.

Please excuse the poor commentary and filming, a television producer or presenter I will never make.

Many of you will say this is just a sneaky advert, and you are of course right, but hey, at least its an educational one that I put some effort into.

 

I'd of had one of you last week if I had enough money

 

hi stu

i understand everything how the standard rear diff mount works...... but the problem you have is when you put an uprated diff mount it does send vibration through the car

i had an uprated diff mount on my 3dr about 9/10 yrs ago was horrible but saying that is was metal to metal , no rubber bushes

the best single mod for a cossy on the axel is the "solid alloy beam mounts" this stops the beam from moving an no matter how much the rear diff moves it will not upset the way the car drive in any form

marco

 

Looks a good product initionally But would there be any movement in a standard mount in good condition? Also would the new rigid mount have any adverse effect on the diff due to lack of movement and any potential shock damage?

Sorry in advance if i am wrong, just being nosey to be honest.

 

could you not just have a fixed mount on the beam like on a impreza rather than the tail end of the diff if that makes sence

ps: you have installed a sissor ramp since i was last up there ( which is a fucking long time ago thinking about it pmsl)

 

escort cosworth's rear mounts are better than sierra ones

 

Thats why it was noisy mate. LOL

We sell those too mate and they do indeed work well but i find them noisy. Also, they are best used in conjunction with the rear mount if you must as they do still allow movement if the triangulation mount is worn due to the huge leverage effect, you also end up with the bolts being used as a stressed member under a lot of leverage which is not ideal. Would rather do just the rear than just the fronts.

That one IS in good condition mate.


No, as the diff is already solid mounted if you look, its the beam we are mounting up to the floor and this bush isn't solid its just a very high shore hardness. I would argue that the amount of damage done to the CWP when your axle tramping away from the lights as you do in a cossie, any NVH damage would be totally counterbalanced. LOL

 

Still rubbish by comparison, will video one when there I next have one in.

 

i wouldent have thought it would be really terrible from a NVH point of view, as any load from bumps travels strait up the struts into the shell anyway..

 

totally agree

about the alloy beam mounts on mine are no worse than polybush beam i had them on my 3dr for yrs and told eveyone to use them best single mod by far

 

The diff is solid mounted to the beam, so this mount IS the beam mount, hence my point about it NOT being a diff mount.


I expect its VERY different here since you came about 10 years ago mate.

 

are the 2wd and 4x4 saff mounts different as i want a mount but im converting to 2wd in the summer

 

No Pete, both the same.

 

great vids stu!

good to see some evidence on uprated items doing their job.

 

Fair play then, thats me well and truly told.Although your manner of replying to a potential customer is a bit suprising, no need for the sarcasm in my opinion, just a normal reply would of done!

None the less,as said beforehand looks a great product

 

Is there not the risk that if the mounts are too rigid you'll start to induce fractures in the next weakest bit i.e. the bits of the shell the mount is bolted to?

 

stu how much are they

 

Got one of the uprated mount but not tested yet - Stu you say you sell the solid mounts but i can't find them on your webshop?

 

I'm currently sorting my rear beam, I have a diff mount on the way,

And seeing as everyone raves about solid mounting the beam itself thought id ask the question, is there a improvement in the solid beam mounts compared to the power flex beam mounts? And is there any difference in feel in the car, I don't want too harsh of a ride?

 

will be ordering one off of you soon, been planning to for a while just one of them jobs i havent got round too

 

yes there 's no movement at all, polys still move jim .. and no difference in noise either trust me .my back end is all metal to metal (traling arms/beam) even the suppension is rose jointed the only thing which is not metal to metal is the rear diff mount.... i wouldn't mind trying the poly diff mount that stu is selling to see what its like on my car just see if it as quite as the standard diff mount

anyway ask your dad he will tell you about the soild beam mounts i had my car since 92 and tyred loads of different things before the internet was ever about was called trail and error .lol..

 

Uprated diff mount and solid beam mounts made a hell of a difference on my saph,no noisier than before fitment either.

 

im guessing this will also stop the delayed arse out slide alot of worn cossies seem to have if that makes sence

thinking about my cars set up it is basically the same as my diff bolts directly to the beam but some impreza's bolt to a bushed plate that bolts to the beam if that makes sence but not vertical but horizontal if you get me

either way considering the age of cossies the options are gonna be fucked and worn mount or uprated fixed mounting but im with marco on the uprate the system rather than just parts of it, nothing can let a good modifcation down more than the worn out bit you dont bother changing

btw aint it about time you concentrated on jap and german car mods too so the future can also have a chance,,,, dont want the cossie lads catching up with us do we now !!!

 

there you go jim 2 of us cant be wrong lol

 

ginge

being honest the back end on a cossy is everything !!!!! weather it's 4wd or not once the back end is set up properly with proper stuff you wont belive how well they handle .. theres a few people on here that have got cossies and i have gladly let the drive my 3dr to see the differece

a standard back end on a cossy is fooking shocking on the handling bad design

you can have your jap or your german but you cant beat the look of a 3dr sorry to say

marco

 

The adjustable rear beam was the best mod though.

 

i know had mine yrs ago

 

Got one of these in my car....I fitted ahmed fast road springs first and thought the car felt 100x better than when it had it's shitty arse 40mm lowered springs......

Then I fitted the uprated mount and it felt 100x better again !

Didn't think it would make much difference but it really does !

 

Cheers boys, ream beam being fabricated as we speak, diff hanger on the way and might just have to get some solid floor mounts now then if they're no noisier

 

Fitted a polyu diff mount from MSD last year, along with R&B/Bayjoo springs.

The difference is very, very noticeable, wish i'd done it 10 years ago as the handling on track is transformed. No noise issues either.

 

Sorry mate, there was no sarcasm there. I appologise if you missunderstood my posting manner as sarcasm towards you personally.


Not in my experience, the rear hanger is mounted to a very substantial part of the chassis.

Hmm, will look into that tomorrow mate.


I found the front mounts very harsh personally, but others say not.

We do more lancers and Diesels than YB's nowadays mate. But if your interested in modern technology, take a look at this amazing new product. LOL

 

Stu, are you now sole supplier of these diff mounts??

Ive seen a few different places offering the same/similar mounts with similar claims. so why should we choose your version over others?? ie whats better about yours?

 

I had solid beam mounts and one of these rear diff mounts ( not bought from Stu tho ) on my black 500

It handled superb on track BUT on the road you could feel every bump and small dip in the road , That bad i took the beam mounts out and returned to std

The diff mount on its own was ok but with the beam mounts it was simply awfull

Perfect set up for a track car but not a road car

all IMO tho

 

I have one and they are bad for NVH, luckily though I was warned it may be before I bought it

Put it in 5th going up a hill at about 60-70mph see how ya like it

 

Mike also sells them, can't see either being majorly different, perhaps the bush inside

http://randbmotorsport.co.uk/shop/De...?ProductID=298

 

ours are quite different from that one above, we used to sell that one ourselves!

the new one is cnc one piece, no welding or distortion of the surfaces to be seen. and also fits them all properly as the thin plate and bolts is standard.

 

Rubbish you have the whole weight of the car acting as a lever on the top hoop of the beam via the diff and gravity/up and down movement, movement will occur the bodyshell is solid but moves also, try jacking one up and watching the door shut with the door open a touch.

hi i am supprised nobody has mention using solid and rubber mountings on the same part ,surely with the rubber mount moving and the solid one not ,the only thing that can is the beam so over time mayby a long time it will work harden and fracture near the solid mount . this may not have happend to anyone yet but it does make sense it will ,you would not rubber mount your exhaust and then put one solid mount in it , if it was me i would try do something about the noise an solid mount it all or rubber mount it all with uprated bushes ,if anyone wants rear mount i do them




thanks mark

 

I don't think there is anything really to be bothered about vibration/noise wise, yes there is a bit, but I forget about it, so it can't stand out that much, I do however find a drumming sound from the tank at a certain speed and certain amount of fuel, so simply stuck a thick sound pad on the bottom of the tank to change it's resonance/frequency and haven't heard the sound since.
Poly filled std ones work just as well at £50, have one running in a 1/4 mile car in Iceland where the temps haven't bothered it at all along with various sierra here, and of course look more std for the bufties.
Some people have been telling of the importance of this component for ages for the same reason.

is that a solid mount?
