Height Adjustable Rear Springs?
 

What is the simplest way to adjust the height of the standard setup rear springs incrementally? Need to be able to adjust the ride height as necessary because race car. Of course adjustable coilovers would solve the problem and I guess that's why a lot of race Z33's use that option but the present MW shocks are good so I'd much prefer to keep those and just adjust the standard located springs height.

EDIT: Problem solved.

Get "height adjustable spring spacers."

And where may they be obtainable from my good man?

It will be quicker to get longer springs locally and adjust height with spacers if necessary so problem solved, thanks for your input mr.sparco.

Just for future reference if anyone stumbles onto this thread. I used Afco on the rear of my Z.

Wonder why those AFCO adjustable perches were not designed to be permanently adjustable just like aftermarket coilovers?

I didn't spot weld the threading. I have taken it apart many times and it hasn't moved under compression. Many of the aftermarket coilovers do not have a second locking seat. I just ran with it and its been years.

Sweet, thanks for that link!
