Experimental Wider Axles 1.26

I did some reworking of the rear 3-link suspension on the D-series and removed the standard live axle as I was unable to correct the axle wrapping issue.

The rear suspension now has longer travel and the axle now has a much lesser shift to the left when it reaches the extension limit. Also reworked some variables to reduce the body roll on hard acceleration, although it is still there with powerful engines.

Also updated the wide 48-inch config to align with the new parameters.

The really wide Prerunner suspension also got some attention to make the front and rear suspension more stable and able to provide more ground clearance
