The post 2014 chassis seem to be more accurately assembled and the caster/camber settings are more consistent than the earlier chassis. When fitting the Empire kit to my 2013 chassis car I had to make a lot of adjustment to get the same caster and camber on both sides but no where near as much when I fitted the kit to the post 2014 chassis. I did need to trim the ends of the upper wishbones to get enough negative camber adjustment though.
The main thing I find with the Empire/Krazy Horse kit is it gives a much more linear cornering steering input with no need for mid corner corrections. Plus no bump steer, which was a major fault with early cars but mostly fixed with the Comfort Kit and suspension mods on post 2014 cars.
