Revised Suspension Geometry

Hi All,
For the 89 model/year Excels, Lotus apparently changed the suspension geometry. Would anyone have any information regarding the changes?
I'm specifically interested to know the changes to the front toe-in and caster, along with rear toe-in.

I have a full workshop manual, given to me by the previous owner, but helpfully the pages relating to the geometry are missing.

Many thanks.

My manual has this page . Is this what you need?

ISTR that it was only the camber at the front that was changed - the last of the upper arms produced have 89MY stamped on them, but I don't think I have any to compare with the earlier ones, but I'll have a look.

Ahh- thanks very much Pete, Stu. It all makes sense now.

I'll use those figures in Stu's reply. Cheers, Martin.

Wasn't this also the year that the rear toe could be adjusted from side to side, by means of the adjustable -position bottom saddle? It didn't alter the overall toe but did allow it to be made even.

Not sure when the adjustable rear tow was introduced but it was on my '88 ('89MY) car. It worked pretty well.
