G61 Lap Analysis

Import a Garage61 lap into Braking Lab, review braking zones, and turn them into guided practice exercises.

G61 Lap Analysis lets you pull a real telemetry lap from Garage61 and transform it into targeted practice exercises. It lives as a tab inside Telemetry, alongside Sessions, Braking Zones, Scoreboard and Coaching Reports.

Navigate to it via Telemetry → G61 Lap Analysis. The legacy route /analyze redirects here preserving any query params.

Why a dedicated tab

Garage61 provides high-quality telemetry CSVs for almost any public lap across iRacing and other sims. Importing one into Braking Lab lets you:

  • See your braking zones with entry/exit speeds, peak brake pressure and a trail-braking score per corner.
  • Generate practice exercises automatically — one per zone, plus a full-lap sequence with corner markers and rest periods.
  • Train the exact corners that lose you time, with the same brake-curve shape you recorded.

You don’t need to be the driver of the lap — any public Garage61 lap works, including reference laps from top alien drivers.

Importing a lap

  1. Open the lap page on garage61.net (requires a Garage61 account).
  2. Download the telemetry CSV file.
  3. In Braking Lab, go to Telemetry → G61 Lap Analysis.
  4. Drag and drop the CSV into the drop zone, or click to browse.
  5. Wait a couple of seconds — Braking Lab parses the CSV, detects braking zones and renders the analysis.

What the analysis shows

Expandable Track Map

Your racing line plotted on the track outline, colour-coded by speed or brake pressure. Corner key points are annotated:

MarkerMeaning
RedBraking reference
AmberTurn-in point
PurpleMax rotation / apex
GreenExit

Markers sit outside the corner with dotted lines to the exact track position so they stay readable at any zoom. Toggle visibility and pan/zoom to inspect details.

Braking zones list

Every detected zone is listed with:

  • Peak brake pressure (% of maximum)
  • Entry speed and exit speed
  • Trail-braking score — 70% release smoothness + 30% peak hold duration

Click a zone in the chart or list to highlight it across views.

Per-corner notes

After saving a lap, click the post-it icon on any zone to record your visual references: brake marker, turn-in point, max speed/RPM, rotation point, trail-braking technique, throttle reference. A yellow icon flags zones that already have notes.

From analysis to practice

Click Save & Create Exercises to:

  1. Store the lap in your account.
  2. Generate one exercise per braking zone — brake curves downsampled to 10 samples/sec.
  3. Generate a full-lap exercise that strings the zones together with corner markers and rest periods.

You are then redirected to Free Practice (sign-in required) where the newly created exercises wait in your Custom Exercises list. Attach your pedals and start training with real-time audio and visual feedback.

The import button in the tab header changes to Import Another Lap — use it to queue more laps without leaving the tab.

Tips

  • Save only the laps you want to practise — lap storage is limited by your plan tier (see Settings → Account).
  • Public Garage61 laps work too — you don’t need to own the lap to analyse it.
  • Pair with Track Notepad — the per-zone notes you take here complement the corner notes in Track Notepad for the same track/car combo.
  • Legacy URL: /analyze redirects to /desktop-telemetry?tab=lap-analysis; the deep-link with query param works for sharing.
  • Sessions & Laps — browse captured sessions from the Braking Lab desktop client.
  • Braking Zones — how braking zones are detected and scored.
  • Pitwall — where you see upcoming races and Race Prep wizard to practise before the event.
