KF2 Spares

[alport]

HI,
I ordered recently a kf2 to have something different in my country (Turkey) I won't have any local support at least for a while so should stock some spares to end up the races. I race only 13.5t superstock on a tight indoor carpet track with medium grip level.
-My budget is limited so I should buy as few as possible spare parts. I assume Wishbones, hubs (don't know ıf I would need all 3 of them ?) rod ends are must have. What about front shock shafts, hinge pins, front bulkhead , belt or any other parts ?
-For setup I will order 5 degree yokes and some springs but don't know which springs should I have for my conditions described above . I'm totally unfamiliar with the car and brand
