Thanks for following up with your results. Too often threads like this just trail off without any conclusions.

Morgan flexibility is completely irrelevant to this due to the suspension design. You cannot compare a live axle with sliding pillars to 4 wheel wishbone geometry in any manner at all.


This statement remains true, but I should have looked at the date on the post I was replying toblush

I intend to follow up again with my results on track in a couple weeks. If nothing else, this can help me learn and defend my setup decisions with testing.

So, I have some good news:

I took First in TT5 over the weekend and turned a new personal best time (dropped a full second, in worse conditions). The car felt more planted than it ever had before. 

As previously posted, I ran with these changes:

  • 1/16" rear toe-in (-3*/-2.5* camber F/R, no front toe, 4* caster)
  • rear wing at -5* instead of -3*
  • stock rear bar connected
  • Racing Beat 1.125" front bar  - soft setting
  • 75% stiffness on the dampers
  • factory NB2 strut bar


  • Rear toe-in is a great idea, I could comfortably rotate the car with the brake pedal at lower speeds, but transitions through chicanes were confidence inspiring
  • The strut bar noticeably improved the way the car felt on the curbs and I heard less creaking from the hardtop when on uneven surfaces
  • I won't be running the front sway full stiff anymore. I did not notice any increased body roll, lack of response, or different tire wear.
  • Steeper rear wing was fantastic. It allowed so much more aggression in braking zones at the end of straightaways 
  • I will be investigating additional front bracing and improved radiator ducting. I had more on-power understeer than I would like and proper radiator ducting will make my existing splitter work more efficiently for more front grip.
