Metric Only

Rear Live Axle Visualizer

2D half-car style engineering tool for launch torque reaction, bump input, pinion-angle change, and rear suspension force paths. Live axle / solid axle only.

Profiles

Saved profile

Suspension Mode

Leaf Spring Explicit front eye, rear shackle, and axle perch geometry with lumped wrap resistance. Leaf + CalTracs Leaf geometry plus an explicit traction-bar style load path into the front spring-eye region. Four-Link Launch-oriented upper/lower bar force resolution with instant-center overlay when available.

Leaf Geometry

CalTracs Assumptions

This first version treats the bar as a deadband axial element after gap engagement. The semantics are explicit here because no local CalTracs notes were found on this machine.

Four-Link Geometry

Simulation

Actions

Leaf debug overlay

Leaf mode uses explicit front-eye, shackle, rear-eye, and perch geometry with simplified effective compliance and wrap stiffness.
