Group,
I believe the standard 280SL torsion bar is 20mm in diameter. I have contacted TLSSTEEL.com to see if they have a pattern for the 280SL bar. Their web site is very informative. If they don't have the pattern I may send mine to them this winter. Is there any interest in a group buy? What diameter should be used? A 21mm bar is 27.6 percent stiffer than the 20mm version. I have the Olson springs. Can anyone say what the various combinations would yield?
