Agree with dt -- I don't know any need for adjustable LCA's except fine tuning, mainly for drag racing.
If you need to adjust pinion angle, do it with adjustable UCA.
For road track, some articulation (ability to twist) is important in the LCA's and UCA; spherical bushing is good for this but can also transmit more NVH
For a lowered car, my understanding is the relocation brackets are important . . . best to do them at the same time.
