The chubs and knuckles in my build are made by Junfac. I believe they are a branch of GMade. apparently some SSD parts made for the SCX10.2 will fit, but I cant personally confirm this. I have only used the SSD front shock hoops.
I don't know that there are any mandatory updates. I often upgrade my front steering parts beacause I like the quality of aluminum not because its necessary. Others may chime in with a different experience
Yep i think junfac and Gmade are the same company.
Looks like a solid kit with not much upgrades needed.
Except maybe for the diffs issues, but i should keep this thing as a slow crawler with 3S power max...
