I to wanted to nail the rear toe thing down
I have two chassis, BMI and an old 2.5mm stock. With both my rear toe was off until I put on 3racing aluminum hubs.
At that time I put on all new parts including pivot balls and everything was good and I was
I never brake rear arm's, I just add shims to keep things tight.
Now my toe is off again
Today I took all the shims off one H-arm so I could move the arm front to back.
I put it on my setup station and found the rear toe moves with the arm on both sides.
Simple solution ........Shime one rear arm until your toe is what you want.
It wont take much difference on one side because the other side moves the other way.
I think if I put on all new parts again it would be closer but I'm just going to shim it in for now.
Don't forget Lazer Guy said it first
