It’s worth remembering that while people do have cantilevered pushrods for offroad - no manufacturer has ever done that, and Automation is all about manufacturer’s tech. Same goes for long-travel MacPherson struts.
Make no mistake, I would love a dedicated offroad/rally expansion, but the system isn’t aimed at that currently.
Agree about the aluminum mass production, aluminum spaceframe, billet crank, hotter cams and especially the proper sequential options (There’s more than a handful of street-legal track cars using them, such as Radical and BAC).
Geared LSD is atrocious for offroading without computer assistance. In low grip settings (Such as a lifted tire) you now have zero torque available. They’re about as good as an open differential there. It’s worth remembering that the Hummer H1 has the ability to lock its axles, it isn’t dependent on the Torsen. Clutch pack LSDs are in the game.
Agree about the springs, progressive springs are usually avoided for that, agree about the downforce and especially agree about the rake.
