D3 mod using D4 part

So im planning on doing a kind of "last upgrade" for my d3 but i dont know what exactly to use or where exactly to go, but what im curious about is using the KPI knuckles 3 racing has for the RWD d4 on my d3


i know some d4 parts can be used on the d3 but i want to know if these knuckles can be used
