The FIA has replaced the additional kerbs located at the final two corners of the Red Bull Ring with timing loops to detect track limit breaches by drivers this weekend.
Last year, the Austrian track's kerbs at Turn 9 and 10 were abused by a few drivers who suffered suspension damage.
With spare parts in short supply, the timing loop will help limit damage while also discouraging drivers from exceeding track limits.
"On the third occasion of a driver cutting behind the red and white exit kerb at turn nine [or 10] during the race, he will be shown a black and white flag, any further cutting will then be reported to the stewards," the Austrian GP stewards stated
"Each time any car passes behind the red and white exit kerb, teams will be informed via the official messaging system.
"In all cases detailed above, the driver must only re-join the track when it is safe to do so and without gaining a lasting advantage.
"The above requirements will not automatically apply to any driver who is judged to have been forced off the track, each such case will be judged individually."
Other changes to the circuit include an extension that has been added to the concrete behind the Turn 8 apex kerb and to the exit kerb.
