I dont have any before pictures, but basically the old (calibra) front struts have the steering arms mounted a long way up them, the new (mk4 astra ones) have it much lower down, and then ive spacered it down further when I rose jointed them.

The pictures you have already seen I would have thought (I put them up a year or two ago when I redesigned it last) are what im describing now, well assuming these are the pics you are thinking of?




Although it looks in that picture that the inner end is a about 10mm higher center than the tca arm, the rear mount for the TCA is higher, so the effectice pivot point is very close to the same height as the toe control arm, and the balljoint as you can see is not very much lower than the effective height of the steering arm (ie the centre of the balljoint compared to the centre of the rose joint)
In an ideal would I would move the outer mounting point of the steering arm lower down to get from too little toe change for me to measure to acutally none, but casting new parts is beyond what im tooled up for and there is no trivial way to drop it further on the setup I have.


In the video of it at mallory with massive steer the arms were mounted totally different, I had made the schoolboy error of mounting them onto the bottom arms which moved their pivot point (well actually it was a mate of mine that mounted them there I was asleep at the time but it was where we had decided was the only place they could go) this was because there was no exposed fixed framework anywhere near to mount from, but I had a "eureka moment" when I swapped them over from the left to the right so that they went forwards instead of back which put them level with the subframe instead of the back of the TCA, and then it was easy from there on in to achieve what I had kept being compromised on doing before.
Silly really that I didnt think to swap them left to right before, but it was just natural to fit them onto the car the same way around that they were on the donor car and once they were fitted up, I coulnt see the wood for the trees that I should have put them on the opposite sides!
