Spring Rate............Confusion!!

[GMP]

If it fits and does not rub the spring guide then you should be fine. I have heard KYB springs fit too.

Preload is the devil. Keeping it to 10mm helps the ride over the trash.

What do you think to fitting a Showa spring in the Sachs shock?

That sounds like a good plan.
Minor differences in length and diameter shouldn't matter. The eibach spring I got was about 5mm longer than the stock sachs - no problem, just a little more difficult to compress on installation. It also has a slightly larger diameter, but came with pressed steel adapter plates to fit the caps. A small amount of reaming of the adapter was required to achieve a snug fit to the shock body - you don't want the ends of the spring to be able to move around sideways. I'm sure your suspension guy would get this right for you.
As you mentioned, it would pay to first make sure you haven't got some kind of binding going on, that is distorting your sag measurements.

Look for a 5.8 rear and 0.48 fronts ... and yes I can hook you up with springs now and valving later.

Sachs can be your friend
