Built from the
workshop bay, not the boardroom.
TrackTheory is a family business, started in 2025, born out of one specific frustration: finding the right parts for builds that don’t fit a tidy catalogue. We race what we sell, ship what we’d use ourselves, and stock the long tail — the head bolts for the platform nobody else lists, the brake pads sized for your upgraded wheel package, the fittings the bigger shops can’t be bothered with.
Sourcing parts shouldn’t be the hardest part of the build.
Hours lost to Google.
Three tabs deep, half the listings out of date, the part numbers don't agree, and the supplier with stock is in the wrong country. We’d been there too many times.
Bespoke builds, generic catalogues.
Race compliance, classic restorations, upgraded wheel packages — the standard catalogues stop where the interesting builds start. We focus on what’s left.
The right part, not just any part.
A brake pad ‘for that car’ isn’t the same as the right pad for your wheel size, your driving, and your sanctioning body’s rules. Specifics matter — we list them.
Four kinds of build the catalogue is sized for.
One-of-one specs, custom part lists, parts that need to talk to each other. Tell us what you’re trying to do and we’ll find the bits.
Grassroots, club, state — we know the categories Australian racers actually run, and the parts that pass scrutineering for them.
Forged, billet, motorsport-grade. Where stock parts stop being safe at the boost or torque you’re aiming for.
Period-correct hardware, factory-spec rebuild kits, the OE-replacement lines that sit alongside the performance gear.
