Red Bull boss Christian Horner wants a rethink of track limits deterrents after Austrian Grand Prix practice.

Drivers were pushing the boundaries around the Spielberg circuit with the yellow sausage kerbs at Turns 9 and 10 catching out many as the slid wide.

The results were pretty severe with endplates and flaps being broken off front wings, while Nico Hulkenberg saw the entire left-side of one wing sheer off.

"It's been a bit of a challenge. We've gone through about three front wings so far; probably about 250 grand's worth of damage, but we're not alone in that," Horner commented between practice sessions.

"There is I'm sure going to be a debate about the angle of these yellow triangles, the way they are.

"They [the drivers] know they're there, I just think the angle that they're at, I think that's what they really need to look at.

"There's been a lot of discussion about these kerbs here over the last couple of years.

"It needs something more substantial that is a real deterrent because the invitation is there for the drivers to try to use it."

Track limits have always been an issue at the Red Bull Ring, with drivers often running all four wheels off the track at Turn 1 during the days of the old A1-Ring.

The sausage kerbs have been a strong yet rather brutal way of avoiding a repeat since 2014, particularly as more corners now have greater run-off.

However, compared to the tarmac paradises like Paul Ricard, the kerbs are arguably the perfect way to penalise a driver for running wide while also improving safety.
