Fitted up my Custom Rear 6kg/mm King Springs last night.
Much better for the weight of the premo pack (and all the junk I carry)
PLus you can do it without pulling the struts from the car.
-Jack car up up as high as you can under the rear control arms
-support vehicle with jack stands
-Remove wheels
-Undo strut top centre bolt with rattle gun,
-Undo HID leveller, swaybar link and hub from lower control arm
-pull out spring
-insert new spring
-jack control arm up slowly and locate shock into top-hat
-install strut top nut loosley
-re-install hub bolt**, swaybar link and HID leveller.
-wheels on,
-sit car on ground and tighten the strut top nut with rattle gun.
done.
**note
the CA and hub bolt holes don't like to line up straight with the lift blocks.
It took a combination of placing the scissor jack between the upper control arm and body, and trolley jack under the LCA and adjusting multiple times to get the bolt in.
And lots of swearing
