The same nine areas the app tracks. Every guide and build log lives under exactly one of them — so what you read here maps straight onto what you'd log there. Pick a system to dig in.
Block, internals, forced induction, intake, fuel, ignition, tuning, intercooler.
Transmission, clutch, transfer case, diffs, driveshaft, axles.
Springs, shocks, sway bars, control arms, bushings, bracing, roll cage.
Calipers, rotors, pads, lines, master cylinder, fluid, bias.
Rims, tires, spacers, lug nuts, beadlocks, TPMS.
Body kit, fenders, hood, bumpers, aero, paint, wrap, rust repair.
Headers, exhaust, cats, muffler, radiator, oil cooler, water pump.
ECU, harness, gauges, traction/launch control, lighting, audio.
Seats, wheel, pedals, harnesses, sound deadening, trim.
The nine systems aren't just blog categories — they're the fixed structure the app tracks your build against. One vocabulary across the whole thing, so nothing has to be relearned.
