Weight Transfer and Suspensions
MP offers a set of smaller T bars than the 6 cylinder cars had/have.
I don't know how far you want to go and money...oh, that M word! It can get to be a nasty item quick. I like the idea of tube front arms. But you can also do the K-frame in this fashion to save more weight.
The lack of sway bars helps in weight. I don't have any on my Duster. The car was built without them. The boxed control arms and torque box's at the rear of the car add weight, but also help keep the car right. Catch 22. Better to have them I think.
