brushless hyper 7 conversion

hi everyone, i am going to convert my hyper7e to a offroad racing buggy so far i have bought:
- carbon fibre shock tower rear
- carbon fibre centre diff plate
- carbon fibre transponder mount
- carbon fibre front brace
- aka city block premounted med. compound wheels
- hyper 9 upgraded knuckles
- spare front and rear lower arms
- spare centre dogbones
- 7075 front shock tower
- 7075 rear shock tower
- losi battery straps
- losi 8e battery tray
- 12,13,14t pinion for less heat without using the castle fan when racing
please let me know if their is any other upgrades for racing a hyper7 at my local track?
thanks Braden
