Your lap.
In context.

Submit native replay and telemetry files from iRacing, Assetto Corsa Competizione or Le Mans Ultimate, or use other commonly used replay, video or telemetry formats. RaceBook’s current upload restrictions apply when you submit, and private paid reviews require files that RaceBook accepts. If a submitted file is unreadable or incompatible, you will receive a full refund.

How it works

Who it is for

A focused next step.

Lap review is designed mainly for sim racers and beginners who want to understand the key points where they can improve.

It is a more accessible way to get professional feedback than remote simulator coaching. If you want a more intensive, one-to-one session with live input and greater depth, remote simulator coaching is the premium option.

Lap Review provides professional analysis and guidance, but no particular lap-time improvement, race result or career outcome is guaranteed. This does not affect your statutory rights or CW Driver Development’s obligation to provide the service with reasonable care and skill.
