Congrats for getting it figured out
BTW, been autoxing my 72 911 for years and what works best for me is 21mm front and 26mm rear torsion bars. 15mm front and rear sway, 2* negative camber front and 2.8* negative rear. Also slight toe out front and slight toe in for the rear. 205/50/15 Hoosier A6's on 7x15 Cookies with the ride height set at 23.75"front and 23.5". Been thinking about trying 28mm rear torsion bars
rear. Good luck
