The FIA has altered the kerbs at the last two corners of the Red Bull Ring following complaints from several drivers and floor damage suffered by cars which ran wide in Friday's free practice sessions.
Romain Grosjean and Felipe Massa fell victim to the kerbs' abrupt profile after off-track excursions, but Max Verstappen was particularly critical of the kerbs' design.
"This is not the highest-grip track and with the higher speeds this year if you have a moment, it is difficult to correct without hitting a kerb or going through the gravel, which a lot of people have experienced today," explained the Red Bull driver.
"The yellow kerbs were definitely a challenge, and I think maybe they are not the type of kerbs for Formula 1, the cars just aren't designed for it."
The FIA has changed the kerbs on the exit of Turn 9, with repairs to the damaged gully strip, while the 'baguette' kerbs have been moved closer to Turn 10 to help drivers who run wide at Turn 9 seamlessly rejoin the track.
