My Vixen S1 came without an antiroll bar. I have sourced a spitfire ARB and the appropriate drop links and mountings but the bushes have me a bit puzzeled.

The Superflex Vixen ARB bushes look like this



but the mounting pate for the Vixen is flat; so I don't understand the reason for the the bulge.

The Spitfire ARB mounting, on the other hand, looks like this:



You can see that it has a curved section, into which this type of bush would fit.

should the Vixen bush be flat?

More like this?



Can anyone put me out of my misery?

If you notice the shape of the chassis on a Triumph that fits perfectly....here is my std. My poly version is the same shape Adrian@

Thanks Adrian, do you do a poly one for a 22mm ARB?

Yes to the 22m, PM me, (I notice on your blog that the caliper hands are in place without tab washers (I know that the TVR never had these as OE but it is a worth while safety upgrade) and Andy, the clamp unit needs to lock up to the chassis (OE Triumph U bolts require cutting down as the TVR bracket is under the chassis tube and will lockout as it is done up), however....I have never been able to lock them down using that type of poly bush as there is give in the material.

Adrian,
You wouldn't have any 25mm dia ARBs in stock for a 1978 3000S would you?

Thanks Adrian. Yes I have already cut the bolts down and they're not fouling the chassis anymore but as you rightly say the bush case is not clamped up to the chassis. I could crank them up some more but I don't think I can get the case to bite onto the chassis. I could insert some spacers which at least would stop any possibility of the bush case rotating within the U clamp.

John, 2nd person in a week asking for that...I could pull the jig out and have 6 made if there was demand, I have no std units left and would most likely do some of those too, let me see if I can get a costing..Yes.
Andy..this is why I only use the round ones....as they can deform and pull up correctly.

I believe Mr Upham's site is wrong about the anti-roll bar. I bought a 1" thick Spitfire bar based on what I read - only to find it was too narrow.

So I think that the Herald/Vitesse bar is wider - the mounts may be different too.

Thanks Kabaman,

This just gets more confusing! I just checked Rimmers and they quote the same part number for all the Spitfires, Herald and Vitess for the uprated ARB - 217033.

I haven't fitted mine yet because I bought the wrong drop links and they have to go back!banghead

Sorry to bounce this back to the top, but I am a bit stuck now.

Looks like I have the same issues as Kabaman had. Contrary to what I originally thoughht, the Spitfire ARB does not appear to fit the Vixen Series 1.




I've checked Spitfire, Herald, Vitesse and GT6 ARBs and they are all the same. Original ARBs are no longer available for these cars and I am told (by Rimmers)that the uprated bars are thicker, but otherwise identical. So Ive come to a bit of an impasse.

Does anyone have any idea whether the ARB on the Series 1 was a TVR factory part or what it was sourced from. If anyone has any pictures of the ARB on the S1 I woudl be very grateful to see them. In fact, if anyone has an S1 in any condition at all within driving distance of J7 on the M11 I would be very grateful if you could let me take a look at it. and take loads of pictures.

if it is just a question of length then surely a Sleeved extension turned up on a lathe will make it all work??

Yes, thanks Neil, I think something like that may ultimately be the answer. Someone also suggested a turned spacer and a longer bolt, but I am not so happy about that idea.

I'd really like to get to the bottom of this before I go hacking things about, but it looks to me like, at least on the S1, its not the Triumph item that is used.

The ARB is not a Triumph part but a Stanpart. Ironic a patent attorney should be asking the question. How much does a Patent Attorney charge an hour?

Sorry Steve a bit slow today obviously, I stuggled with that and had to re write my post about 4 times before I got it. I obviously need to go find another bottle of Tiger beer

Do you happen to know which "Stanpart" it might be?






Just for interest I went off to the Patent Office web site to find out who owns the Stanpart trademark now,and it British Motor Heritage Ltd.......... judge
