Conversation Between houston and wriffwraff

Hello Houston. I've been out of the nitro 1/8th scale truggy scene for well over five years now and thinking to reboot with a Kyosho STRR Evo 2. However, I'm struggling to ID and prioritize initial upgrades. From what I can tell, the "out of the box upgrades" are the front and rear inner suspension hinge pins and "E" clips, as well as the front carriers and knuckles, correct? Unfortunately, looks like the front and rear bulkheads have assembly shafts with "E" clips too. If so, I'd need to replace those as well. Again, if so, would you happen to know of the fix for that (shafts and locknuts)? My last concern are the chassis braces... do they hold up or are King Headz braces needed? Just want to address the "out of the box" upgrades and then let the track drive the rest of the upgrades.
