Hi Martin

Well spotted [8D]

Intresting mod, allowing for caster adjustment and converting to 'A' frame wishbone suspension.

That is a serious brace the gent has made,







nice bit off engineering, do you know the gent concerned, i hope dont me posting the 2 pictures [8)]

Cheers John

I like the front brace, it's a beast. But, if you do anything to lighten or remove the front bumper of a DHC, you need that because the bumper acts as a sort to torsion bar to the "frame"

Beans,

I thought you just mocked that up. Did you actually implement it?

I am going to implement it when time allows ...
(fixing damage to the DHC at the moment, which probably will take till the end of this year)

Do you have a problem with fore and aft movement of the strut as the suspension goes up and down, because there looks to be a difference in length with the two parts of the new arms?
It might cause you some bump-steer problems unless the geometry is spot on. I speak from personal experience on a couple of cars, one was mine many years ago and the other someones else's rally car more recently. It caused spooky handling on both until we realised what was going on.

There will always be for/aft movement of the strut under bump/rebound.
But that will be less than with the original set-up.

Most important to avoid bump steer is that the pivot points from the TCA and Tie Rod are in a line (so TCA has same length as Tie Rod) and the TCA and Tie Rod run parallel.

Grinnall did something very simialar to all this on his later cars. It was called the "wishbone" upgrade and is found on the round style cars especially.

Hello Martin

It looks very stiff - think it brings a little stability - how it looks with the water-cooler?

The engine is a bit down to the left is this normal ? if so how much are the degree in about..

I always thought the engine is taken horizontally (oil pan) [8)]

Frank,

It isn't my car, so I can't comment on the engine. Sorry.

The only problem with most similar front end modifications is fitting a new anti roll bar in there, with similar or greater roll stiffness. With an uprated suspension such as these it will probably require a stiffer roll bar, & really needs to be adjustable to get best value from the modifications.

Triumph Rover Spares, in Adelaide South Oz had a similar highly developed suspension, developed on their very successful Targa Tasmania car. This was depicted on their web site, & available on a made to order basis.

I noticed this had a nice drop link roll bar incorporated, although I can't remember if it was adjustable.

I'm sure the set up offered would have been developed using roll bars of a number of thicknesses, to get something to suit Ian, the owner. However he is a very exuberant driver, & I expect something a little softer would suit me, & many other drivers better.

The site is well worth a look.
