   How many splines do you have to turn when lowering on the torsion bar to lower it 45mm?
   
   If its any help, i will have 16/45's . Its on a 98/99 VTR. And will eventually be getting dampers too.

   been told 1 spline = 20mm mate! if that helps! although i should warn you splines or notches is the wrong way to do it!

   splines is the wrong way
   
   do it the right way and you can lower as much as you want dow to more or less the mm
   
   you will need arch work on them wheels

   there is no set measurement for the splines method, its innaccurate guess work

   use a trolley jack on the arm to set the height mate once the bar is pulled out eg measure the distance from hub to arch before removing, pull bar out, lift - 45mm on your measure and wack bar in, or do it -50 as u gotta compensate for the arm weight

   As its been said, splines are not the best way to do it and i think you can end up with 1 side lower than the other

   from when my mate did mine you can only do them a spline at a time, as the torsion bar doesnt fit when you do it in halfs, when we measured it from the arch to centre of studs it affected it by about 30-35 but youve got to take into mind the weight of the arm but thats what the rough measurement is. my car got lowered 60mm at the front, when i lowered torsion bar we did it 2 splines and it now sits horizontal nearly! so its right!!

    splines is wrong how many times does it have to be repeated.
    
    Do it the correct way as described as above and you can lower or raise the car by ANY amount to within a mm

    you're doing it by pulling the trailing arms off, which is wrong. do a search for the other 4000million lowering threads to find out how to do it correctly.
