forget about that rear suspension, not a fan of 1/4 ellipticals
Do a cage first, so that when you get to the tough stuff that the rest of the rig is ready for, you are protected. I always regretted not having a roll cage in my rig. (still not finished, so I guess I still regret not finishing)
Linked front with coilovers is fantastic, and that tubework on the fenders isnt too bad either.
