IRS alignment setting for wide rear tires

[boygenius]

I think that only the 1969 beetle had double sided spring plates while every year after that had an easier to work with single spring plate. The single spring plates only use three while the double spring plates use 4 bolts.

When you enlarge the the spring plate hole you allow the TA to rotate either counter-clockwise or clockwise which changes the camber of the rear suspension.

Am I correct???

Thanks for the info on the spring plates. I thought that because the slots in the spring plates are elongated horizontally already for toe adjustment that I could elongate the holes in the TA vertically and that way I would have adjustment both up and down and front to rear without over sizing the spring plate holes.

But I still need to know if I use the middle bolt for the rotation center or the forward one closest to the torsion housing.
