Subaru

A lot of the best parts for a rally Subaru are Subaru parts. The STI six-speed in the wagon is the clearest example we have: fitting it, with fresh differentials at both ends, made second passes through the same stages consistently quicker on a car and a driver that had not changed. Knowing which factory parts are worth hunting — and how to read the numbers on them — is most of what our buying guides are about.
