Queensland.com – Sandy Creek Raceway (Warwick) description
On kart setup: where a manufacturer published a table or guide for its own chassis (Birel ART, IPK/Praga, Arrow, OTK/Tony Kart and the OTK-group brands, Kosmic, CRG, Italkart) the value is tagged Factory or Manual. Energy, Parolin, Kart Republic, FA Kart and unlisted brands had no published table I could find, so they use General guidance — what those manufacturers broadly agree on. The manufacturers disagree in a few places (front ride height, caster on very low grip, axle stiffness on low grip, rear torsion bar in the wet, tyre pressure for understeer); those are flagged so you can test one change at a time. Track type (short/tight vs long/flowing) is inferred from the published lap length, except Sandy Creek which is described as one of the fastest tracks in Queensland. Setup values are starting points — check your kart’s own manual and your class rules for legal widths and parts.
Bridgestone YDS and the OTK/CRG wheel entries have very little published pressure data, so they're treated as close to the generic baseline — a rougher starting point than the others until you log your own numbers against them.
On left/right split — what's a rule of thumb vs what's real: cornering weight transfers onto the outside tyres, so a track with more right-hand corners loads and heats the left-side tyres harder (and vice versa) — that side gets set 0.15 psi lower cold as a
starting-point heuristic. But there is no published, authoritative left/right psi number — the CRG factory manual's own method isn't a formula either: run equal pressures as a baseline, then after a session record each corner's actual hot reading and nudge that corner's own cold fill until all four rise a consistent ~2 psi. That's exactly what the Measured pressures grid in the Session Log is for.
Your own data beats all of this: your sync code (top of the page) carries your session log and remembered track settings to any device you open the same code on. Tap "Remember grip & direction for this track" once you know a track, and log your measured pressures every session — that becomes more accurate than any generic source here.
