Doctoring Front Arb

[sutol 0]

Did anyone ever get around to altering front or rear arb to make adjustable ? there has been talk of a DIY job

Have done search and to buy one looks expensive so I thought maybe it wasn't too difficult to fettle your own.

I'm thinking to stiffen it up would save having to go negative camber, and whilst the engine is out and I'm replacing the

bushes anyway then perhaps I'll have a go at it. can't be that difficult....or can it ?

If you're up for some experimenting I came across the description of a US patent for a torsion bar stiffener that looks very simple to make and also looks like it should be quite effective too. Might be worth playing with?

BTW you should be stiffening the rear rather than the front on a 205

That is for a bar that is fixed at one end like a Morris Minor or my Isuzu front suspension (no springs) but an excellent idea and an excellent site.

I suppose that as those ideas are not patented in UK then it is OK to use them

I was going to do both, but never done it on a 205 before.

Is there a problem with stiffening the front, I was hoping that it would help to stop roll but maybe I will just be creating problems elsewhere

its not just a 205 'rule'

 

on a fwd you stiffen the rear and RWD you stiffen the front

 

AL

Yes, or the rear suspension of a 205..... However I don't see why the same idea wouldn't work on an anti roll bar too (which is just a torsion bar after all)

Absolutely. Although I think it would also be ok to make one for personal use in the US too, you wouldn't be able to sell them though.

The arb is only fixed to the wheels and for instance does nothing at all during straight and level braking to stop the nose dipping.

To stiffen the action one would need to shorten the fixing points at the wheel end, if you get what I mean.

 

I think after due consideration that I will go the route of stiffer front springs and leave the arb alone.

Maybe I'll have a look at the back one when I get around that end. It would be nice to be able to thread the ends of the arb and fit threaded tube to it for ultimate adjustability Think I'll patent that

People also fit thicker (stiffer) front anti roll bars (like the 309 bar) and I don't see why this modification wouldn't have the same effect?

 

Its of more value on a 205 at the rear of course, but if this works it would be a simple bolt on mod that would fit most cars, I'm amazed they aren't in production, patents are probably the reason though
