Had very high expectation before event, as Mclaren dealer has changed the new ABS sensor and units for me. However, the ABS kicked in when brake pressure surpassed 30% and locked up. Car spun at turn 1 at 160mph in one session. 

Not great overall conditions, had to be adapted myself using less brake during the rest of the event.
