MONACO, May 28 (Reuters) - Formula One rivals hope to discover some of dominant Red Bull's most closely guarded secrets from photographs of the underside of Sergio Perez's car after it was craned off the Monaco Grand Prix circuit. The floor is the most aerodynamically sensitive area of the car, with ground-effect sculpting responsible for much of the performance. Monaco marshals typically use cranes to clear stranded cars from the metal-fenced track because of the close confines and lack of runoff. "So the teams will be all over those kinds of photographs. "There’s a lot of very excited aerodynamicists up and down the pitlane looking at all of that."
