Ah, so what your talking about is what we call an ARB (anti-roll bar) :icon_smile:
And you right a 3 wheeler without an ARB is very unstable when cornering.

That's true of three-wheelers with one wheel at the front -

Bit of an extreme example, I know, but the reverse trike is actually very inherently stable and they handle really well without castors.

Ideally the rear tyre's contact patch should equal the total contact area for the front 2 tyres to prevent the rear end from breaking loose mid corner

I think there may be a little more to it than that. The car's CoG, fore and aft weight distribution and overall weight amongst a number of other things will determine how much work the rear tyre is being asked to do......and you might consider how much you want the rear to contribute when applying the brakes.

Roadster 6th December 2015 16:10

Yes you are right Oxford there are !00's of pages written on the subject safe handling of a three wheeler broken down into the various configurations but I was trying to address the one aspect that could be considered at this time as Micky is deciding on the rear arm set up

BRA for sale on ebay http://www.ebay.co.uk/itm/BRA-Kit-Ca...-/151886347576

oxford1360 11th December 2015 06:37

Another one of those "90% completed" projects that has 80% of the work still to do.

Body and bonnet are Aluminium sheet with fiberglass boot lid, scuttle panel and engine cowl.
It's all held together around a steel cage frame SAMMIO style.

Here's one I made earlier :biggrin1:

I painted the fiberglass panels and front mudguards sky blue, then sold it to a guy in Kent (sorry no final finished photo).:icon_redface:

Plus the "you can just use the V5 from another 2CV" may not be how the DVLA will see it either. :eek:

Links to a review of the original Leighton : http://www.bra-cars.com/Leighton_-_A...both__web_.pdf

I can see the attraction of retaining the 2cv chassis, but the effort/cost taken to find/restore one (to retain the V5...) may well be less than that to use the bespoke chassis, particularly given the handling benefits of the Leighton suspension mods.

£400 new, and galvanised to boot -

As for retaining the V5, it's a standard, replacement chassis so under DVLA rules the V5 can be retained if one of these is used to replace an original chassis that's rusted so badly that there's actually nothing left of it at all. Trigger's hammer and all that.

Mistrale 12th December 2015 12:47

I didn't realise new chassis were that cheap. But not much cheaper than a bespoke one, particularly given the handling benefits of the bespoke chassis.

Motorbike IVA is also much simpler and cheaper than car IVA...

Paul L 12th December 2015 14:57

Mr T - Nice link to the replacement 2CV chassis. :cool:

And just for clarity...

The key difference between what Mr T is saying above and my reply in Post #29 is that the Ebay seller was proposing that you keep the non standard chassis in the BRA he was selling and use the V5 from a different 2CV donor car to get the BRA on the road, which is not allowed.

Cheers, Paul. :)

I would cost twice as much to build a bespoke chassis than to buy a standard replacement chassis.
Plus the bespoke chassis would be heaver, un-galvanized and produce no significant improvement in the handling, I know as I have built both examples :nono:

The IVA or MSVA require a lot of extra money, time and effort which will put prospective builder's off :nono:

All ways remember the No1 rule when building a kit car KISS, becaus it works :icon_smile:

Triumph Special 12th December 2015 17:36

A good idea this, I wish you every success with it.

micky1mo 17th December 2015 19:24

Just spoke to Chris at Tribute and the "Leighton" moulds are now being laid-up so I'll be collecting a body next week . :whoo:

Only wish the new Alpha was so near :cry:

A Great Initiative
 
Where did this project get to? My first ever car was bought in Belgium, the basic 2CV with bench front seat and a roll back roof (no fancy levers to do it from inside). It was that, or the Llada, which was even cheaper. I know it is a bit premature, with Chris at Tribute about to start my Z3gato. However, I am thinking about a project to start later next year.

Currently it would be a Lambretta LI150 refurbishment from wreck to refurbished wreck. (Seriously, as a 16/17 year old, I did just about everything mechanical on a scooter. This was way, way back in the late 60s.)

But a 2CV based 3 wheeler, wahay! :eusa_dance:

micky1mo 13th May 2018 07:57

The LEIGHTON project/moulds were sold on is it was proving to expensive and to time consuming to continue with. :eusa_shifty:

I do still have a new 2CV galvanized chassis, engine gearbox, axles and original fiberglass LEIGHTON body, bonnet and boot if your interested?:smile:

Barber 13th May 2018 08:04

Is that the model currently available on internet for quite a high price? If so, the total bundle would be too much for SWMBO to stomach after the Z3gato. However, I may come back to you later.
Cheers

£700 gets you the lot!!:icon_lol:
