Umm.. With shims you'd be raising the rod ends as they are mounted from the top..

 

 

Perhaps someone should do 'inverted taper' steering arms and mount the ends from the bottom up...

 

Bye, Arno.

 

Install a RH steering arm on the left hand side and vice versa
 

[Scuffers]

are you mad?

 

seriously....?

Have you read the posts  before mine !

 

For test purpose only  (static test)

[Scuffers]

yes, but think about it...

 

the top ball joint is a taper fit too... so unless your going to drill it out, the heights will all be wrong.

[Exmantaa]

to all the above. Somehow I got in my mind that the joint was on the bottom of the steering arm, but it is obviously located at the top...

 

To Scuffers; this has nothing to do about being right or wrong. It's all about measuring the influence of these height changes on the bump steer curve, as this information seems to be hidden in a very dark vault...

(But moving the pivot point from the top to the bottom of the steering arm will be a major movement and probably will throw it miles off the curve. We need some subtle changes here...)

 

[Scuffers]

consider that bump-steer is a function of the relationship between the top wishbone and steering track rod, any change to either will affect it.

 

ie, move the ball joint hight in the steering arm will move it the same as changing the hight of the steering arm joint.

Intuitively I would move the pivot point of the track rod to get more in line with the top arm pivot. For some reason I can only upload to 8.41Kb, so no pictures, but the track rod is connected to the upright by an arm that is moved inside quite a bit. That makes the radius of the arc it's moving through shorter than the top wishbone. And causes the track rod to pull the upright inside. So that would be the first thing I would look at. Question is: why is it this way? Ackerman?

[techieboy]

You'll either need to add the pictures into the Gallery (link at top of page) or host them externally at Photobucket etc, once your attachment space has run out.

[Scuffers]

track road is shorter than the top wishbone, thus the bump curve is a curve not a straight line.

 

(EP do a new rack which is shorter to make the track rod length the same as the wishbone, thus you can then have linear bumpsteer,)

 

please remember that bumpsteer is something you need to get accurate steering feel and response, also remember that different tyres react more or less to this, so some fine tuning is usually required.

[alexb]

They also offer exactly what I meant: http://www.elisepart...eering-arm-kit/. So moving the track rod pivot point more in-line with the top arm pivot point. It's not the most elegant solution, but it might work. Dying to actually measure it tbh.

 

Does anybody know if this fits the VX?

[techieboy]

It does. I've got it fitted. Cliffie had it on his Time Attack car and I think there's a few others with it fitted.

I have the part (full kit) but not fitted to car yet.

Yes fits the vx, but make sure you get the correct track rod ends, we had to do a bit of modification to mikes/mine as the hole on the sleeve/collor was in the wrong place for the vx and you could not wind them on enough.

[alexb]

Can't seem to find the right rod ends to use with these. The standard ones (tapered) don't work, but can't find the 'high quality' ones that are used on this arm. TBH, I don't mind spending some money to see if this works (for me), but the full kit is a bit steep and like to measure first before going the whole way.

[2deano5]

 They come in the kit?

[xco]

I have fitted. I think that the bump-steer on damaged roads it's less than before, but I'm not totally sure. I was two months without driving the car before fitting the EP kit and I don't remember very well how it feels the steering before... Also I don't know if it's correctly fine tuned. Front height is at 112mm (with 195/45/17) and only one height adjusting washer was added to track rods, the thinnest.

The threads of my track rods were poorly made and I had to arrange them to fit them on the steering rack.

Yeah, but track rods are service items. You'd expect them to be available seperately. And EP has a number of track rod ends available, but all seem to just fit the steel arm with a tapered hole

You can buy replacements of these specific track rods, they are separately available in the same page of the kit.

[alexb]

On the same page I see S1, S2 and Genuine Lotus track rod ends. All of these are tapered. At least I think so. The ones that are part of the kit are straight as far as I can see.
