DeDion Rear

[E90400K]

If Slate wants to use as much part commonality as possible, why not just go struts all around and use the same suspension front and back? Use a suspension link in place of the tiered for the rear hubs. An IRS should easily handle a 1,400 pound payload.

Pickup box intrusion maybe?

Depending on how it's designed, a De Dion suspension could use the same struts as the front suspension.
