Racing Line Lab · physics-simulation estimates

Barber Motorsports Park,
re-solved live.

Leeds, Alabama · 3.72 km · 2.31 mi · clockwise

Open Barber Motorsports Park in the Racing Line Lab and the browser re-solves the speed profile on the computed racing line as you change bike class, mass, power and grip. Every figure below is a simulation estimate on OpenStreetMap-derived geometry — not a measured lap.

Fully interactive free in the Lab — presets, sliders, ghost laps and PNG export.
