The catalogue
Rally parts
Parts marked On our cars are ones we run on Betsy, Toshi and the wagon across a full Australian season — described from driving them, not from a brochure.
Not for sale yet. This is a catalogue — no prices and nothing to add to a cart. Ask us about anything here and we will tell you what we know.

Not sure? Use the VIN or chassis number
Australian-delivered cars have a 17-character VIN. A Japanese import has a chassis number instead — GDB-012345 and the like — and that one tells us more, because the prefix is the chassis code.

Buyer’s guides
The catalogue says what a part is. These say how to avoid buying the wrong one — the ratio arithmetic, the part-number grammar, and what a used listing leaves out.
Why a GDB needs a 3.545 rear diff
The final drive has to match the transfer gear, or the centre diff destroys itself. The arithmetic, and how to read it off a listing.
Reading Subaru STI six-speed gearbox numbers
What TY856 codes and 32000A assembly numbers tell you about generation, DCCD and front LSD — and when they contradict the listing.
Buying used drivetrain parts sight-unseen
What a listing has to state before it is safe to bid, why clutch-type beats helical on stage, and the Japanese terms that carry the real information.
