The stock spur is good but just in case you should have one I damaged mine (my fault) and still using it but remember it is very difficult to get techno parts at most hobby shops so I would be prepared. Ditto on the front shock tower inch pins front and rear arms and shock shafts.
I have also lost a wheel nut and the toe insert in the hinge pin brace, broken a lower spring keeper, lower shock eyelet. Very happy with this car but crashes happen and better to spend some $ to be prepared
