Be careful of the Spec-R. Hit or miss quality. If you're going to get one, buy at least one extra gasket and service pack of gears, you're 100% going to need them!
The genuine Yokomo diff is expensive, but like most things of quality, it's because it's worth it! In the end, it will last longer than the same cost of Spec-R parts.
