Note that while there is no factory rear camber adjustment on a Mk2 Supra, it is possible to adjust the camber by adjusting the height of the rear subframe relative to the body. There are 4 attachment points on the subframe, and they are insulated by large rubber bushes. If you cut these bushes down or remove them entirely, this will result in more positive camber. Conversely, you can add extra spacers in there to get more negative camber.

So...remove the bushings to straighten the wheel. and reduce tire wear-but increase ride harshness Is that right? Would this also lower the body height slightly?
I have done the above mod however you also need to cut down the bush inner sleeve. The cross-member on my car now sits up against the chassis and you get a lot more drive train noise through the car. It does not change ride height as the springs still go between the chassis and the rear trailing arms.

Because this is not a very nice solution I am now looking to modify the rear trailing arms to provide adjustable camber. We are looking at a similar setup to that use for the toe adjustment - except we will use the outer mounts for camber.

The rear cross-member (I have a spare) will be modified by extending the holes in the outer mounts down. We will then brace using a similar adjuster setup as used for the toe adjuster. Hopefully it should be enough to pull a couple of degrees moe positive (currently mine is at 2.5 degrees neg - 1/2 a degree I think would be nice).

Has anyone done a similar mod at all or done something different? This is the best way we can see to get the adjutable rear camber without rose-jointing the rear end.

Yup - exactly the same as on dattos - that is where the idea came from (used to rally one back in 1987!!)

Nowadays you can buy an adjuster kit to weld on as well - so it is easier to get a big screw-driver in there to pull the arm down :) If it does not stay with simply bolting we will then change so that camber washers can be used.
