I purchased the performance plus system from VanSteel with some mods.
I have the off-set T/A, just had to relocate the e-brake bracket. The half shafts remain the same.
I kept the rear spring and used the QA-1 adjustable rear shocks. Everything bolted right into place with no problems.
Here is a good tip.... Call the supplier of the suspension parts and talk to them about the driving that you are planing to do and what your expectations are about the performance and handling that you want. I did this with VanSteel for my set-up. They put together a kit based on what I wanted.
What I can not tell you is how it rides. I am still working on my car. Some day soon.
