Estate rear suspension

Post by BX Bandit »

Does an estate run softer than a hatch? I know it depends on what spheres fitted, but I was told it's a no-no to put estate spheres on a hatch, so why not estate cylinders+spheres on a hatch? I know they are a bigger piston size in an estate.
Thoughts oh knowledgeable ones?

I'm guessing that estate one's are slightly different pressure because you're more likely to load up an estate with heavier items than the hatch. Now whether this means they are softer or firmer i'm not sure, i suspect there wouldn't be a massive difference. I'd suggest giving the guy's at Westroen a call, i'm sure they'll be able to tell you the differences & what it might do to the softness etc...When you find out, let us know :)

The estates have 500cc spheres but same orifice as hatch spheres. It was Pleaeiiieeaaiieedeiiiis that said estate spheres on a hatch resulted in 'arse dragging'

Simple enough to try, just wondered if anyone else had tried it?

Basically, is an unladen hatch harder than an unladen estate? 500cc spheres on estate would suggest yes, but they have bigger displacement in the cylinders, so for every bump, your shifting more LHM, but with a bigger sphere to absorb it. That is as far as my brain will allow me to delve before it starts to hurt.

Anyone driven both estate and hatch? Matt? Kitch? Doc? Tim? to name but a few

unladen I'd say the difference is negligable to be honest mate.
Not that I've ever driven an estate with fresh sphere's on, but I haven't ever noticed an appreciable difference betwixt hatch and estate.

I havnt noticed any difference switching from any of my BXs except when sphere's get a bit old. Those on Sophie will need doing soon.

AFAIK BX estate rear spheres are slightly bigger to take the extra weight and carrying capacity, when Ive ordered them new from GSF they always asked if the car was a hatch or estate.

Pretty lucky there Tim :) I thought it was GSF who usually just put a green round thing in a box and posted it off without worrying if it was the right one !

I replaced rear spheres a couple of years ago (estate) when it started bouncing around too much at the back end and I didn't really notice any difference between the new ones and what I remember of the old ones when they were working properly. I suspect, though, that the ones I fitted were for the hatch - they were supplied by GSF - and Mike thought the ride was a bit softer than Timex on the way to the pub at Gaydon. I'd think the hatch spheres on an estate would make it a bit softer, but looking at the spec differences some time back I don't remember there to be much difference in them anyway.

looking at the GSF chart i posted above

it says
estate in petrol and N/A diesel rears are
500/40/1.10
GSF part No.
N45346

and estate in TZI/TRI/TD SHOULD BE
500/40/1.00
GSF PART nO.
n45346

GSF part No. the same for both??????

It's not unknown for aftermarket parts manufacturers to make the decision that one part is close enough to cover a number of different applications. For example the water pump on the XUD engine has a different OE part number for the turbo and non turbo versions, but pattern part manufacturers often (always?) list just one to cover both.

The spheres on all of my cars are from gsf, the two tzds are very soft on the rear, they bottom out very readily. Maybe they are a bit of a compromise.

you have the wrong spheres on the rear then,

years ago i fitted some second hand front spheres to the rear of my GS estate, after which if you just looked at the throttle the rear would hit the bump stops,

They are the ones that they supplied and the front and rears can't be mixed up because they are different sizes, the front ones are only 400cc.

they should be 400/55/1.40 on the front and 500/40/1.00 on the rear for a TD as in the chart above

What do the numbers 400/55/1.40 relate to? First must be capacity in CC but the others?
