The reason for the different spline counts is to allow more precise adjustment. 40 count on the inner 44 on the outer.
Quote from Pelican "SWISSMADE"
"On the SC (not sure about 911s) the torsion bar has 40 splines on the inner end and 44 splines on the outer end.Moving the inner end 1 spline makes a difference of 9° which means about 8 mm. ride height.Moving the spring plate on the bar's outer end makes a difference of 8.18° which means about 7mm. in ride height. A 1° change in spring plate angle makes about 1cm. change in ride height. All very theoretical......I did mine about 4 times till I got it right."
