upper rear suspension arms

[stocktake]

I have now fitted a new pair of these complete with new springs. rear droplinks and can confirm on my car the ARB doesn't foul the wishbone and when sat on the road the distance from wheel centre to arch is spot on. back of car feels solid and secure.
Going to run for a week and nip back under and check all is well, I don't envisage any problems and it wasn't as bad as I thought it would be. Still glad it is done though

I know, coat, then door.

Well I suppose I could use the foil trays from the jam tarts, and blutack them over the rusty holes in the original arms

Seriously though, who can spot the fault?

Forget the antiroll bar Dave, and make a special tool from a thin piece of card, then feed it down your new arms..........I'm hoping this is isolated to the arms that I'm not likely to fit anytime soon

They were probably made somewhere like this.

Or more likely Bernie and Leepu at Bangla Bangers

So this was a while back all this was kicking off.

I noticed exactly the same thing with my new arms.

Did Xpart give an answer or do anyhting about this? Was anything resolved at all ?

I test fitted the spring obviously, and the isolator fouls the side of the cut-out of course, just like others.

Every single one I see online is the same, so folk are just putting up with the isolator fouling? Under the wieght of the car Im sure it flattens out somewhat, but its still shocking quality. I am loathe to fit them, but have no choice with the car off the road while I do the entire rear suspension.

I have seen the quality of Indian drop links, and it makes the Chinese stuff look like it came from Bentley.

The lower isolator is to be remade slightly smaller in diameter from the original

You can prune a small amount from your original ones without difficulty though Ross

Wow,

What a cop out! :p

If only they had made them properly in the first place.

What did they have to say about the "welds" where you could insert cardboard?

Whats their lead time on the isolator?

Edit:- Thats me almost done then with the ZT. Cant tolerate this level of support any longer, the quality of the parts is embarassing now. If they were £40 each fair enough, but to charge £130 PER ARM for that.... no chance. I'll likely sell my new arms then on here at a loss but hopefully will sort someone out who really needs them and wants to save a little on the retail.

Soon as these come up at the right price...

(to Brian or anyone)

would moving the location of the spring isolator locator not alter the geometry of the spring? (with the isolator being so thick, I cannot see it 'letting' the base of the spring 'pull' it back or crush it back to the designed position)

I imagine then that it could actually alter the spring into a more positive angle, in keeping with the travel of the upper arm. With this, I could imagine as the upper arm rotated on its axis, there is the possibility of the isolator lifting at the wheel side when under tension. If this did happen, then at best, the rear suspension could become 'squidgy', maybe even knocking against the cup in the chassis. At worst, the tail of the spring could be forced inside itself, maybe even snapping prematurely.

Below is a PS drawing hopefully illustrating what I mean. the image may exaggerate the reality of it though. Even if the handling is not compromised, I would think there is still a possibility of having excessive wear on the tyres with no means of adjusting it out.

Relative to the car the springs position is not changed I believe.

It is just that the ARB mount and spring hole centre are different relative to the visual center of the spring cut-out.
