RE: warhead hub conversion
The pro-line adapters are 23mm and will not fit on the evo cause its uses 8mm stub axles and the pro-lines were designed for the maxx trucks and revo and they use 6mm stub axles not sure thats the exact size but I do know they use smaller stub axles so the adapters wil be too small unless you drill them out which could be a real pain in the *****.
Get the savage x ss 17mm hexs and nuts and they should fit since the evo and savvy both use 8mm stub axles...
