In RRR Evo 1 no, but in Evo 2 the diff from the previous models is known to cause some issues. Which model you have?
The new Shimo version/model comes with the front diff and is based on Evo 2. You may check the manual for part numbers, can be found from Kyosho's International site.
Personally have upgraded the chassis and top plate of my Evo 1 WCE to Evo 2 and otherwise using Evo 1 parts. No issues there as far as I can see.
