evening all. Was having a think about the know issues with the diff arm snapping, and obviously I want a solution like the rest of you. So I have an idea and i'd like your thoughts on the subject.
in the mx5, the diff, gearbox and engine are connected in one solid structure, tight and stiff. where these connect to the subframes, they are on rubber bushes to allow the vibration and road shock to disperse.
On the roadster, you have no subframe. I think Stot may almost have the solution with his solid mounted bracket. the theory being that the solid mounting will prevent the diff from twisting. however, I think that by having the supporting bolts running straight down to a new plate at the bottom of the diff cage, any rotational force is transferred laterally down the bolt, preventing any shearing force to the support bolts. I would still use rubber bushes to the diff arms, so any small twisting of the diff is absorbed by the bushes, as in the original car.
What are your thoughts?
