I haven't done any measuring yet to confirm anything except the ride height width. 50" outside to outside of the front tires, running 2/3 offset front rims.

I bought +1" +1" metal tech chromoly a arms for 16.5" shocks. Iirc the z400 spindle shaft is shorter, cause I read to run z400 hubs on Zilla spindles the shafts needed to be shortened. Running 1/4 offset rims would narrow the front by 2".
