All depends on how much abuse you'll give it. Personally I go OTT with spares and recommendations, but id rather not be caught short. Then ofcause there are certain spares which are essential. There are no real weak points if you build the car up properly. But leave the slipper loose and the spur gear will melt.

Essential spares:
The M3 cap head screws, especially the 12mm ones for the front of the front wishbones. Check these regular as they bend.

Front wishbones

Rear wishbones

Front shock tower

Rear shock tower

Front & Rear shock tower mounts (unless you upgrade to alloy)

Front hingepin and purple alloy parts

Wing mount 'O' rings

Belts.

Ballstuds and cups

Shock shafts

Spur gear



Not essential but worth having:

Driveshafts

Diff balls, thrust and plates

Bearings

Axle drive pins

Chassis top deck

Servo horns (upgrade this to an alloy ringed version)

Slipper pads

C hubs

Caster blocks (unless you upgrade to the 7.5degree alloy)

Rear hinge pins

Rear hubs
