the alloy diff is larger fluid capacity, doesn't leak, rotates true as its a machined part, and the shims stay in tact which in turn keeps the diff operation consistent. I've actually tried to run the plastic diff vs the alloy diff in the same race day. The alloy diff felt more planted with same track speed. I run alloy diffs in all my current Schumacher rigs.
