Hold your horses, that is a very bad idea.
The FA vs. RA springs have totally different characteristics and can not be swapped. This will put you ride and handling in dangerous territory.

I meant the 90 CQ swap into front, and fronts to rear, mentioned above. Your thoughts?

In general I am not a fan of this type of shade tree mechanics.

What car do you actually have? It would be a good starting point to give you actual advise. The only thing that I got so far is that you want to lift whatever you have up. Am I correct?

OK, 84 4kq.
I would try the 83 UrQ FA springs. They where approx. 15mm higher then all face lift vehicles of the MY85. You might even get more out of it since you will be lighter in FA compare to the UrQ. Others then that ,this is all the B2 platform can offer. I have no clue about B3 or 4. that would be trial by error.

As long as you go FA to FA and RA to RA you should find something.
Use the 4k shock mount bearings on top. Don't use the blue UrQ once. These are 10mm shorter.

Happy wrenching.

I trust anything Derracuda says, so I consider this to be the best method if you want it as high as you can get without some custom fab.
