OK sports fans!
The Rush SR Baseline Setup recommends 0.25mm of toe in on the rear.
I've tried and tried to get a consistent suspension setup but, each time I setup the car the toe and to a lesser extend the camber changes.
So, today I took things apart and measured them.
First I pushed/pulled and the 3 and 9 o'clock positions and found ~1.25mm of play
Removed the tire and noted this when looking from underneath the car looking at where the rear trailing arm connects to the hub/upright
Stuck a feeler gauge in the gap and came up with ~0.43mm
So then I measured the width of the opening on the upright
Then the rod end spacers
and the width of the center of the hiem joint
So.....
Opening on the upright ~23.85mm
The hiem joint width ~13.90mm
It would appear that the rod end spacers are a bit undersize ~4.75mm and ~4.78mm............. each of these needs to be 5mm not undersized.......
So for my car I could do with two set of rod end spacers that are 5mm in width.
I'm also going to replace all of my hiem joints with Aurora Bearing with the PTFE lined bearing surface as my current ones have excessive wear.
I looked for Rod End Spacers with a 10mm inner diameter and a 5mm length with no luck.......anyone have a source?
Hopefully with new hiem joint ends and proper sized rod end spacer I'll be able to get a repeatable suspension setup!
P.S.
this is where I have additional end play, but I understand these are "wear" items and need to be inspected and replaced when there's end play...
