List,
What a curiosity this is.....a rear suspension that transfers power to the
wheels through a rubber donut.
I'm familiar with the term but had never seen "it" until last week when I had
a chance to see "it" (assembled and dis-assembled) on a GT6+. At first I
thought how clever it was to use a big rubber bushing donut to absorb changes
in axle torque and loads to the rear wheels but after I saw the results of
the rubber bushings delaminating from their metal washers, etc, I began to
wonder why Triumph did this......well, I'm guessing that money was at the
heart of the decision.
I have a few books that address Spitfire & GT6 history but thought I'd ask
the forum that question....."Why did Triumph use rotoflex in lieu of perhaps
a sway bar/swing axle Spit suspension or even an IRS setup?"
