Red Bull have been involved in a bit of an un-holey controversy in the last couple of weeks, first with holes in the floor of the RB8 being deemed illegal and then Charlie Whiting ordering the team to change the car's front wheel hubs after it appeared that cooling holes were providing a possible aerodynamic advantage as well, against the rules.
But the team insists that the changes they've had to make to the car won't affect their performance this weekend.
"We were not afraid that it would have a big impact on performance," said Sebastian Vettel after clinching pole position in Canada in dominant form despite the changes the team had been forced to make to the car as a result. "I think generally, the car works as a whole – not the hole in the floor but a combination of all the parts together!
"It was a bit of a shame that it went one way and then the other, being declared illegal, then legal and then illegal, but in the end we never feared a big impact on the performance of the car," he said. "It's not just a hole in the floor that makes all the difference."
Vettel confirmed that the changes had been made in time to ensure there would be no grounds for a protest from other teams during or after the Canadian Grand Prix weekend.
"We changed the car," he said. "I think there wasn't a lot of time to react ... We had to close the hole or slot or whatever you call it. It seemed to work pretty well without the hole.
"It was good fun today and even without the hole I enjoyed qualifying a lot," he added.
Vettel added that Red Bull's strong showing in qualifying wasn't the result of any other major new upgrades on the car making up for the absence of the holes.
"We've seen some teams bringing a big step here - Ferrari did. For us it was nothing big. We are always pushing very hard to improve the car," he said. "It's not as if we have major changes and it's not as if we've had a completely different approach. I think we're able to learn from the mistakes we made in the past, we did it in the last two races, where qualifying was arguably not fantastic for us."
The world champion insisted that the recent controversies weren't going to put the team off continuing to push as hard as possible in 2012.
"I think we still have to make sure we get the best out of the car that we can," he said. "We see that this year is very tight so it's up to us to make sure we use our package as well as we can and sometimes it might be good enough for the front row like here, sometimes maybe not good enough, but then we still have to make sure that we are very close."
On the evidence of Saturday qualifying in Montreal, its so far so good for Red Bull - but the real proof will be in the Canadian Grand Prix itself.
