Uprated anti roll bar

From my recollection of a timeline I fitted the uprated roll bar before any suspension mods and found the difference amazing as per sdibbers description. I did not feel any real difference in comfort.
Since the car has had many coil spring changes, and adjustable damping.
The worst thing for ride quality degradation is solid bushing the bell crank, for very little gain !

Not really, the HD springs aren't very HD. the ride compromise is at the front end. Obviously you will lose ride quality, otherwise you wouldn't need independent suspension.

Mine transformed the handling. I no longer have to panic, or indeed slow down when going through sharp corners, like little roundabouts. It's been in there for 11 years now, not a single issue with it.

So now the arb supplier is sorted, the arb itself has had many years of positive use by many individuals, all with positive feed back, has anyone considered experimenting with a rear arb ? Or is that Facebook territory and too risqué for the forum ?

Cat thrown into pigeons :oops:

I remember a guy in Australia has one fitted, I think they’re on here but can’t remember who.
The dedion is effectively one big arb, and mounting points would need to be flexible enough to deal with the track increase/decrease of the sliding tube obviously.

I recently fitted lateral locks to my V70 front sway bar after noticing it easily sliding through the uprated poly mounts I fitted sometime before. Difference in handling was huge, I must have got used to driving it with the extra roll

Some thirteen years back Alan Ramsbottom at Classeparts offered a rear ARB.
From his 2007 price list;
"Rear Anti Roll Bar Kit from £485.90. This kit can only be priced after we know what else you are doing with the rear end."
So it has seemingly been done before. I've not seen the set-up. I would be interested.

I have an anti roll bar from the jag rear end I got from fleabay - where the diff came from.

Not quite sure how I would fit it, or if I could be bothered TBH.

There was someone who found a Peugeot 306(?) rear ARB could be used. My guess was they attached the open ends to the trailing arms and mounted the cross bar to the rear cross member.

Hey Jim
Forgive me for being uneducated on the De Dion, but as the sliding joint is not splined how can it be acting as an ARB ?. Surely the wheels move independently ?

How about a fixed length De Dion, with no joint ? The length of track being catered for by CV joints in the driveshafts, lateral location by Watts link fitted to the De Dion tube.

As far as i know this is the setup that Alfa used, and also the P8.

The Peugeot rear bar is what the Irish rally guys first machined for their front arb, and I’ve done the same thing for my car.

Hmm, you’ll have to forgive me as I did post that without really thinking about it. You are right of course, they do move independently or else it would be skating all over the place.
But they are still tied together. Obviously both wheels are kept parallel as far as toe is concerned but rotation of one elbow/side of the tube can only go so far surely? The trailing arms and springs are free to move independently, but once one is in compression the other I’m sure is equalising it to some extent?

Here’s one of Simon’s old videos which shows it working nicely. There seems to be very little body roll and a lot of suspension articulation.


My answer is I don’t know, and I’m sticking to that lol

The car in the video did not appear to be put through any vigorous cornering exercises. Suspension did seem very effective at soaking up bumps though.

Yes true. What I do remember Simon telling me was how flat his car was under hard cornering after his work lowering and sorting the front and rear damping/spring rates. He mentioned interest in a bucket seat and harness as he was finding himself sliding out of his seat regularly lol

He's gone and formed a niche subgroup over on the dreaded book of faces, a subset of the Rover P6 Club page, called 'Rover P6 Modified'. Fairly active group of enthusiasts, some P6 owners from far and wide I've never knowingly encountered on here, with some very nicely improved cars. Those Aussies seem to know a thing or two about how to make these cars look meaner, go quicker, and deal with twisty bits well. I don't in any way want to malign the folk on here, but as has been noted it is a bit staid, and a bit quiet. It took me over a decade before I caught on that the internet action was happening elsewhere!
