Just an advance note to let you practise a bit: there's a reverse run at Suzuka GP.
EDIT: I practised with Legend - Hypercar Club - 15.3 (H2H). But any TT, Hunter, Speed Record, H2H with any car will help you to learn the reverse direction. You can drive them without service as long as you like.
EDIT 2: If you practise, don't forget to switch off Steering Assists. They are switched off automatically in the event.
