Sebastian Vettel, Red Bull, Monaco 2012Red Bull motorsport chief Helmut Marko does not think the FIA's ruling over Formula 1 floor regulations will handicap Red Bull Racing at all in the Canadian Grand Prix.

The reigning champion team will have to modify holes in its RB8's floor following a clarification issued by the FIA this week. Several of Red Bull's rivals had considered protesting its design during the Monaco GP weekend, which saw RBR's Mark Webber take the team's second victory of 2012.

Marko played down the significance of the FIA directive and said it would have no impact on Montreal form.

"We had not planned to use this floor in Montreal, anyway," Marko said. "We had prepared a different configuration using a flat version of the floor. Therefore we do not need to modify the cars in Canada."

He insisted the FIA decision was not just a ruling against Red Bull, saying: "This concerned other teams too, not only RBR."

Red Bull had used the floor in question in the Bahrain, Spanish and Monaco GPs. The team is the only one to have taken more than one victory so far this year and currently holds a 38-point constructors' championship lead. Drivers Sebastian Vettel and Webber are equal second in the standings, three points behind leader Fernando Alonso.

Marko added: "We are not disturbed in our race preparation by this decision."
