( CNN ) -- Formula One is a sport where tiny margins can be the difference between success and failure , so it is no surprise a small hole in Red Bull 's Monaco Grand Prix winning car has got rival teams reexamining the sport 's regulations . Mark Webber clinched the Austrian-owned manufacturer 's third consecutive win in the principality on Sunday , but questions have been asked about the legality of Red Bull 's RB8 car .

The FIA , the body which regulates the sport , states the floor of an F1 car must be impervious , a rule many teams presumed meant it must be free of holes . The official rule is as follows : `` All parts lying on the reference and step planes , in addition to the transition between the two planes , must produce uniform , solid , hard , continuous , rigid ( no degree of freedom in relation to the body/chassis unit ) , impervious surfaces under all circumstances . '' Webber wins Monaco Grand Prix . But the RB8 's design , which has been cleared by FIA scrutineers and has been running since April 's Bahrain Grand Prix , features a rectangular slot in front of the rear wheel of the car . `` In Monaco there was much discussion about the legality of the Red Bull 's floor , with speculation that rival teams were considering lodging post-race protests ( none ultimately did ) , '' read a statement on the sport 's official website . `` Despite the fact that Red Bull have been running the design since Bahrain with the blessing of the FIA scrutineers . '' The slot increases downforce at the rear of the vehicle by offsetting the negative impact the rear wheel has on airflow over the car . Latest F1 standings after Monaco GP . And the Red Bull is not the only car to feature a modification aimed at tackling this problem . Both the Ferrari and Sauber cars feature slots in front of the rear wheel .

With no team launching an official protest , the RB8 , complete with slot , can be expected on the grid for the Canadian Grand Prix on June 10 .
