It would be good to compare the MV6 and Elite parts in case there is a significant difference. Only thing I can think of is that it mounts the inboard ends of the track rods differently to compensate for the lower ride height but I'm not even sure if that's possible without poking my head under the car.

I cant see that you would ever want different lengths, that would give very odd effects.

I would ahv thought that the bump steer is less because the suspension travel on the harder setup is smaller, this gives less wishbone movement and consequently less interaction from the track rod ends

I always have trouble explaining things I think I understand in my head, let's say for example, that the stock ctr pivot points do not pivot on the same plain/centre line as the wishbone pivot point? And the lowered sports chassis center tie rod does, or along those lines/if that makes sense/if you see what I mean/sawtafing

The only thing that can be different is the section from the pitman arm/steering idler to the track rod

First time in a while but this has sent me to my Haynes manual, a picture page 1.5, picture of the underside.

So we have strut suspension with a wishbone pivoting along an axis more or less defined by one horizontal (front) and one vertical (rearmost) bolt (give or take some compliance in the bushes).

And I'd expect the steering centre tie rod to reflect the line of that axis, but in the picture the ends of the tie rod at either end seem to be outboard of that axis.

Shows what I know.

But it says to me there is not a completely direct relationship between the length of the steering centre tie rod and the pivot axis of wishbones, and one variable here could be the ride height.

So if I'm making a fule of myself here then it's not a first but I do think there must be some significant difference between the standard and MV6 centre tie rod due to the different ride height.

Sort of along my line of thinking in my previous post ... I'll try and explain it different ...

If the wheels are the same - as I think they are .. the hub heights are the same, so the track rod ends are the same height.

As the ride height is different the steering input is at a lower height on the MV6 as the body is lowered ...  therefore the angle from the steering arm to the trackrod end is different .. \ (normal) against - (MV6) grossly exagerated but its all the keyboard will let me do !!) This gives a different effective radius ?? - the horizontal distance between the two I - I might be the same .. but the angular difference I \ I greater

So the "lever arm" of the steering is different thus giving a different "feel"

random thoughts part 2 ...

looking at the above mentioned pic in haynes, only the steering idler joint and pitman arm joint line up with the wishbone pivot center line, cant tell if same hight, the ball joints are outboard, as said. But that whole section moves left right with the steering of course. Geting a hedache now...

also, fitting lowered sports chassis suspension on mine, which lowers the ride hight, has made no differance to the the feedback sensation at the steering wheel with stock centertie rod.

So that, to me, says ride hight makes no obvious differance....i guess?

Dunno any more, that was my intuitive thought but my head aches now too...and on the third glass of Sunday night red...will try again tomorrow... :-? :-?

I think that post 2000 MV6 has the shorter pitman arm and idler arm. Which could cause an end-of-travel interference needing to be cured by a different drag link.

I swear that on my 2001 MV6 it rides no lower than my other Omegas.

if the chassis is really lower ( i.e. lower ride height ), then a slightly longer centre drag link would correct any bump-steer, but I would imagine that the effect would   be very small if any. Basically, if the centre drag link ends are on hte wishbone pivot axis, then there will be no effect - and they are just about.

Measuring Kevins mv6 wheel arches to floor, they are/where all 15mill lower than my Elite. Which is as oof legend.

Now, with lowered sports chassis fitted my front end sits 15mill lower once settled. Back still has self levelling shocks working, and tech 2 won't recalibrate it for some reason. However the back only needs to drop another 8mill or so to achieve 15 mill as well.
