The rear suspension of an FMC is trailing arms connected to torsion bars. I had previously added Timbrin rubber bushings to help things out in the rear. Given the minimal weight change and the strength of the original suspension, I have not had to do any suspension changes.
What a great project. How has the new engine affected the load on the axles? Have you had to do any suspension modifications?
