   Just done my 3rd rear axle lowering today (all on the same car, lol) via the "correct" remove the torsion bars hold the arm at the right height and pop the torsion bars back in (LHS first then RHS).
   
   I've lowered 40mm and 20mm but based on the splines lining up I can't see how anything other than multiples of 20mm are possible.
   
   How do you do lower the rear by say 30mm or 50mm ????

   Rotate the bar till you feel the sweet spot.

   Yes I did that but always seemed to end up at either 20mm or 40mm with nothing in between.
   
   I read somewhere that 40mm is equivalent to 2 teeth/splines - so logically 1 spline turn is 20mm.
   
   Maybe I'm just missing something

   You don't go by that. You set the trailing arm to the correct hight and support it with the jack then insert the bar back in. Then just rotate it until you feel it slips in. then tap it into place and refit the eccentric bad boys.
   
   Only go by splines or notches = 20mm when you don't know what the fuck you are doing.

   lol - I don't go by the splines.
   
   I set the height then put the bars in but noticed that to get the bars to actually go in I had to raise or lower the arm so that the splines lined up in order to get the bars to slot in. The heights of the arms that corresponded to the bars slotting in with the splines lined up was either 20mm lower or 40mm or 60mm. When I set the height to 30mm there was no way the bar was going in as the splines didn't line up - hence my question.

   what them two said, just keep rotating one spline at a time till it goes in at your chosen dummy damper length.
