Hi, I race a X4Pro and the only parts i've needed to replace are:
1 set of diff gears
1 front tower holder
2 front shock shafts + ends and a spring
the diff gears was my fault as the slipper was too tight, the others are from hitting other buggies
make sure you check the screws that hold the steerings hubs, i have lost one of those then when i landed it ripped the steering hub off, but again that was my fault...
because of those i only keeps them parts in stock..
so a very strong car
