To agree with one of the above comments - there is little point in setting all the suspension accurately unless the front sub-frame is solid mounted (and not with poly mountings).
On my 'S' I just run the 1.5 neg fixed length lower arms and use the Mini Spares offset bushes to achieve the same both sides. I also use adjustable tie-bars.
The rear I set using shims, filing the radius arm pin outer bracket hole and welding a large washer on to keep it all in place.
