Here's the content if you cant view. Makes good reading and is probably the same as your issue.

There should be an equal number of threads showing providing both trackrod ends are the same type. if one is further in than the other it moves the rack out of center, this creates the effect of different length steering arms which also creates bump steer in different directions on each side. you need to make sure the rack is properly centered before setting the tracking and then make sure the front wheels are facing the same way as the rears. Most of the competition cars that i set up arrive with rack out of center and once put right people are surprised at how much better it drives. Its quite an easy problem to sort out and it surprises me that so many people ignore it.

Absolutely agree with this.
On other stuff I work on there is a plug in the rack which can be removed, and then a dowel dropped in which locates into a drilling, and centralises the rack accurately. I don't know of this feature on a 205 rack so the only way to do it that I am aware of is to measure the turns of the wheel and do it that way.
If fitting a pair of new track rod ends this is how I do it.
Screw both in an equal amount that you think will be somewhere near, then ignoring steering wheel position turn the rack so the wheels are straight and check the tracking, ignore the steering wheel position. Then adjust both track rods an equal amount, either shorten (more toe out) or lengthen (more toe in) BOTH to achieve whatever overall toe you desire. Once you've done this and locked the track rods off, then you can centre the steering wheel up by removing the nut and indexing it round on the splines.
If you are adjusting an existing pair then really the easiest thing is to remove them completely, give them a dose of grease to make them easy to adjust now and in future, and then do as above.
And this echo's my point as i got my tracking done 3 times by a garage in leeds as it never felt right! and as i ercall all he did was to set the steering wheel straight with a bar and hook then adjust the tracking - completely ignoring the central rack position.

There is definitely no slot for a pin on a 205 unfortunately. I figured all this out for myself a while ago after several tyre fitters failed to get my pug right. I ended up blagging a couple of hours on my local garages ramp with their laser aligner and it took me ages to accurately centralise it. The people at the garage thought I was insane because they would have just set the toe to the book figure and put the steering wheel on 'straight'
Once I had got it right I found it cured some nasty bumpsteer as Eeyore describes but it also makes the steering weight load up evenly in both directions, previously it would feel light if you turned left but heavier if you turned right due to the messed up ackermann effect.
