Could someone explain in great detail just how the lenght adjustable links would address this problem.

There is an age old racing trick for live axle support.
To restore bottom link attitude we'd need to lower attacment location on axle as much lower as we've lowered the suspension. With 50mm's lowering job we'd be happy with at least 50mm lower mounting point on an axle.

I have seen on a Japanese Toyota site special brackets for rear axle which relocate mounting holes just that much lower.
Here are linked pictures I spotted on american 4AG forum (where I posted this same suspension dilemma).

Factory stock rear axle mounting bracket. An extra fixing hole drilled:

In a proper fully adjustable 4-link configuration top links need adjustment as well in similar manner. I am currently looking into this. Will install modified rear axle in several months time.
To present info I have on link attitudes they can be divided into 2 main categories; optimised for either launch traction, or neutral performance in mid curve (in racing environment).
