Wow - shpub's ARB drop links
Discussion
Got a set of shpub's anti roll bar drop links for my birthday. Only fitted the front's so far, but the difference is amazing!!!
Prior to fitting, any steering input seemed to cause the car to roll before it actually started changing direction making the car feel a bit marshmellowy! With them fitted, the front stays totally flat. I actually went looking for roundabouts yesterday and drove round them a few times - there's so much grip and the front just keeps biting and turning into the corner (and i was really pushing too).
I'm sure the grip has always been there, but it's never been communicated back to me in such a way as it is now. Wanted to fit the rear links over the weekend also, but the old front links were an absolute nightmare to remove.
My car is now really keen to turn into corners - I strongly recommend the links to everyone. Thanks shpub

I don't know if Steve has answered this at all, if he has apologies for raising it again.
On the rear kit, why does it need two joints, when the original only has one rubber ball and a bush through the wishbone. I'm sure there is some logical explanation and I just haven't quite got my head round the mechanism. In my mind's eye, having a single joint means that the wishbone can still articulate freely over bumps, but the body roll still causes the bar to load up in tension.

Glad you like the links... jsr.
Iain....
The reason why you need two links is that the paths travelled by the wishbones and the ARBs form two circles in two different planes. The original design use the rubber bush for the ARB plane and the bolt and bush through the wish bone for the second. The bolt/bush arrangment has to pivot to cope with the movement and in some circumstances, it will try and twist the plate which is why the plate sometimes break. This is caused by the fact there isn't any pivot there and the rubber bush is simply crushed to provide the movement. End result is the ARB force is absorbed by the bush instead of being transmitted to the wishbone. This will continue until the bush can't move any more and then the ARB starts doing its magical stuff. The second joint provides a pivot so that the wishbone and arb can move how they want without twisting the plate or wasting force to deform that bush.
