Model overview

This iteration makes the C3 trailing-arm solver one adapter behind shared test, signal and KPI contracts.

Coordinates & signs

Canonical coordinates use +X rearward, +Y vehicle right, +Z upward. Positive camber moves the wheel top outboard; positive toe is toe-in.

Calculation state

Edits mark the current result STALE. Run suite preserves the previous view until a newer revision completes.

Current solver scope

Trailing-arm vertical and paired roll kinematics are enabled. Generic rigid-body, steering and compliance solvers are explicit future phases and show unavailable—not synthetic—results.

Evidence boundary

KPI names and behavior follow public RACE material. This application does not claim proprietary equations or regression windows.
