I was just thinking because I would use it for touring cars as well. But yes the slop is probably going to throw out measurements anyway.
On the plus side my 22 drove like a dream considering it doesn't have any weight in it at all, all the changes where very minor, so think I'm going to play with subtle things for the next meeting. Hopefully I will have the new balls for the diff as that sounds like a bag of nails at the moment. Do you ruff up the surface of the diff rings or just fit them with diff grease as per the manual?
I'll hopefully get round to posting a setup sheet this week.
