8 spyder's are better, since they got an alum casing which the lightning diff's doesn't have. Meaning the caseing won't twist under power, and that's what kill's diff's.

And if you really wanted too, you could throw a set of steel spyder gear's in there to make it even stronger.(instead of the molded one's) Which aren't expensive.

But they key question is, how much power will you put on them?
