Where to buy spheres

I've a late BX19D estate and would like to try some of the older, softer, spheres. GSFs website lists only one type of sphere. Maybe Pleiades do them but its not clear from their website. Does anyone know a current supplier (new or recon) of a fuller range of spheres? Thanks, Eric

Fitting estate spheres to a saloon will soften the ride at the expense of handling and is a cheap and easy way of achieving a softer ride.

I run CX spheres on the TD, has no negative effect on handling, but improves the ride no end.

How come they have an advantage, is it because the volume & damper are different?

So I take it the reverse happens if saloon spheres are fitted to an estate?

Correct. In fairly basic terms;

Spheres designed to support a heavy load will be significantly softer when they're only supporting a light load.

Vice-versa, spheres designed to support light loads will be harder when they try to support a heavy load.

It's actually rather more complex than that, requiring analysis of the cylinder cross-secitonal area, the sphere volume, static pressure and damper hole, but as a rule of thumb works fine.

What spec sphere would you recommend for a tzd turbo & would you change all 4 spheres & would u use a normal accumulator one a cx one as well? Cheers

Well, my cars a Turbo D (tuned to hell and back), runs very happily on CX spheres (GTi spec) and has a standard BX accumaltor sphere, although I know people that run Xantia acc. spheres..

True - my BX had an XM accy and TD estate corners and was smoooooooooooooooth, the Xantia had its rears replaced with TD estate ones and made no end of difference to both the towing and ride.

On the Hooligan I am running TZD spheres on the front and valver ones on the rear, its firm but supple, ther seems to be a difference with ABS too?
