Rotoflex Adjustable Wishbone with Anti Roll Bar

Recommended Posts

Went to an autojumble and bought a pair of adjustable rotoflex wishbones with an anti roll bar that bolts to each wishbone and aparently fixes to the chassis. Initially I  thought they were home made, but the closer I looked I could see that there was more to these than I first thought, and more like a well made kit. Vendor said they were Triumph Tune items and that they were listed in their catalogue. I did have an old catalogue late 80's but binned it by mistake with a load of CCC mags.

Anyone got an old TT catalogue with any info. I'll upload some photos when I get a chance.

I do have an old TT catalogue though I don't recall the items you describe.  Pics would help.

I did once own (briefly) a complete pair of SAH Tite-a-Turn rear driveshafts which could be described as "mock rotoflex" though they may have predated rotoflex to be fair.

They had adjustable lower wishbones, though I doubt they'd be mistaken for actual rotoflex ones.  I had been thinking about putting them on my Herald but the engineering quality was just so dire, hopeless, appalling etc I decided I like the swing axles better.  Happily I found a buyer so enamoured of all things SAH that he bought them anyway.

A friend at the time and successful sometime  Spitfire racer in the TSSC series made some tubular lower wishbones, 1" longer, adjustable and with ARB mounts to go along with his stretched  (2" wider track) roto rear end.  They were really rather lovely (he was a welder/fabricator by trade) and I do wonder what happened to that car - and the man himself for that matter.

Like these?

Fabricated and fitted to SofS.  Now replaced by a stronger version - see pic 2

Actually looking at them again they would probably fail the rotoflex coupling, just straight not curved, so confused. Single spherical bearing chassis end rubber bushes hub end. Brackets bolted to the wishbones for the roll bar to attach to. Was told they were fitted to a gt6. I'll take some photos tomorrow.

Possibly intended for use with the sliding spline/UJ driveshaft conversion that cropped up  occasionally. So could work with a CV shaft too.

Here's a pic. Could this be part of the SAH Tite-a-Turn kit you mentioned? I do have TLD sliding shafts on the Vitesse purchased off of here years ago. I bought some tube a couple of years ago to make some wish bones up but not got around to it. Saw these the other day and was intrigude,  but not knowing exactly what they were didn't want to pass them by, so took a chance. I've not seen nothing like these before.

Now seen on a decent sized screen and I'm 99% sure they are part of an SAH tite-a-turn set.  Sorry if this wasn't the news you wanted!

The wishbones are indeed re-purposed front uppers.  The set I had came from a gentleman who got them on a Mk1 GT6 he bought.  He was initially pleased to see them.  4 rotoflexes and at least two sets of wheel bearings in very few miles later he refitted swing axles.  The rotos used were Imp ones (woefully undersized) and fitted without any compression (ie you took the bands off to fit them) so had no chance of the survival.  The wheelbearings were two swing axle style ball races fitted in a machined aluminium housing (hard bolted to an adapted standard vertical link) and had no side load capacity at all, leading to interesting and rapid failure.....  Absolute tat.....

When I initially saw them I thought they were a  DIY job,  cut down triumph wishbones, but the more I looked I could se they were definitely not made using cut down small chassis Triumph parts. They are not symmetrical and totally different width and shape to the small Triumph front upper and lower wishbones. Cant find any reference for the SAH tite-a-turn so if anyones got any pics or links, would be good. Here's a close up compared to Triumph upper wishbones.

The plot thickens!  Perhaps they were never lower wishbones per se but a variation on the 'camber compensator' theme.

That looks like it Hamish. One side anyway has The R on one side and L on the reverse, the other has no markings and is slightly different, but probably out of the Triumph parts bin. 

I am sure Nicks right, that this is part of an SAH set up. Don't think I can make any use of it for my purpose, may offer if up, but unanswered questions on overall dimentions adjustment bushes, etc. So probably go ahead with making my own.

Yes they were a different shape and only one had the R and L stamping. The other whilst not marked is still part of the designed pair.

The marked one always went on the front with the correct letter uppermost to match the right or left side of the car. This I understand was part of the castor that was introduced to the later 4s with angled and handed trunnions. This gave castor and camber.
