Telemetry Lesson

What Understeer Looks Like In Telemetry

Understeer appears when steering demand increases but front rotation does not. Learn to diagnose it before it costs the whole straight.

Primary Signal

Steering Up, Rotation Down

Steering angle rises while minimum speed does not improve and throttle reapplication is delayed.

This usually means front load or line timing is not supporting rotation.

Secondary Signal

Exit Delta Growth

Delta often begins to rise after apex because steering remains high and throttle confidence is late.

Likely Cause

Early Turn-In

Entering too early forces steering hold and front scrub.

Likely Cause

Brake Release Too Soon

Dropping pressure early unloads the front before peak rotation demand.

Corrective Action

Later Apex Plan

Delay peak steering, taper brake longer, and prioritize earlier exit throttle.
