The bartalone mesh plate is needed if you are jumping,if not it's not as needed but still good,you do need to have you clutch casing to have a hole drilled and tapped to allow yo to screw the mesh plate on
The other needed things in my opinion are centre and front braces,as I managed to flex my chassis with the stock braces so much at bashfest the front drive shaft came out and bent
The other good thing but not crucial is the rock armor servo brace,it stopped the servo flexing inwards when you brake
I'd also recommend the team fast eddy easy adjust servo saver and jam nut,top make sure the stock servo saver screw doesn't unwind
