410V3 if it's a pro version just get the ally 14mm hubs, ally servo saver and the ally front and rear gearbox sets standard part number TD310039, then its good to go.

210

Ally shock towers front and rear (personally use the Cream ones)
ally rear 14mm hex's
also there is the carbon steering rods
carbon rear camber upgrade


then weight as required, other options are the Cream front bulkhead either ally or brass and ally FR mount last ones are just tuning options!

Spares the 210 is pretty bullet proof apart from the rear diff but several posts on here as how to sort that, so just standard parts like wishbones, bearings, shock towers, and the 410 pretty similar!
Hope this helps just my opinion though!
