Kyosho ZXS-Evo question.

[RJJ]

Hi guys needed some help from the Kyosho experts on here please

I have seen 2 types of boxes for these, one has team Kyosho on it and others are plain.

Also seen gold shock caps and bottoms with yellow springs while other kits have blue colour shock caps and bottoms with silver springs.

Was their a change during the production run, anybody know why the differences from Kyosho and is one rarer than the other, box and shock colours etc.
