W123 alignment quest

When I got this 300TD it was not allignable, probably from an accident. The problem was camber R side and it burned thru two sets of Michellins to my distress. Hated that.

I got the custom K-mac lower control arm bushing that has a TON of camber adjust as you can see. $350 from australia for 2 of them. Its the same as factory lower control arm bush that is used for camber adjust except the bolt is WAY off center and inside a central steel barrel that also rotates freely inside the plastic, (Not rubber as from MB) very tough plastic bushing that fits just like the Low control arm bushing from MB.

Now the alignment is as shown on the print out.

In the photo ( of the right control arm bushing) you can see it is adjusted to push the control arm bushing as far as it can away from the center line of the car .... that is maximum negative camber. That puts the R side just at the maximum allowable negative camber.

Same on L side its adjusted for Max negative camber which wears the inner edge of the (by the way) brand new Michellins

I can see no reason it could not be adjusted for dead center on the factory range recommended by MB

Same with caster,

The PDF link is the result of the latest adjustment on the alignment rack.

This has been a long journey, closing in on perfect alignment.

Any comments??

Thx in advance
