Thanks to prateek for some inspiration: http://www.eurobrick...showtopic=81238
I tried something new with the chassis, it's just two big 1x16 technic beams, but I spaced them so there's a 5-stud wide gap between them instead of 4-wide. This helps widen the track (distance between tires on the same axle) while still keeping the body itself 8-wide.
Got lazy so it isn't finished, looks good so far.
