I definitely understand upgrading to the new angled rear diff housing (it dramatically cuts down on rear driveshaft wear), but a rear diff housing as a spare??!? You've broken a diff housing in racing?
To the original poster's question:
Hingepin holders or upgrade to aluminum. (I've broken 2)
Rear shock tower or upgrade to EB48 tower (I've bent 2)
Front control arms (I've broken 1)
