I adjusted the front two to the suggested starting point (5 turns counter clockwise) now how do I get to adjusting the back two?

 

you have to pull them off. they adjust at the same location as the fronts, on top. you can get extensions so that you can adjust them from the inside of the car

 

these are the extensions

raise one side of the rear, remove the rear wheel.

remove the two nuts at the top mounts (rear shocks) and pull the
mounts down and hold.

remove the protective cap, fit the 3mm d-spec adjustment tool, turn,
put cap back on, let the shock extend by itself into place, and tighten
the nuts snug, but not super tight.

do the other side.

im at 1.5 turns from full stiff front, 2.5 on the rear. feels good.

 

Thanx, that's exactly what I needed and they are actually pretty cheap!
