Gianmaria Bruni has lost his GT2 pole for this weekend's Le Mans 24 Hours after his Risi Competizione Ferrari 430 failed scrutineering.
Bruni pipped the works Chevrolet team to top spot with a time of 3m59.233s, but a post-qualifying check found the car's rear wing Gurney flap to be 2mm too low.
The team maintains that the wing was in a higher position for Bruni's qualifying run on which the lap was set, but has accepted it made an error.
Bruni, Pierre Kaffer and Jaime Melo will therefore start from the back, leaving Oliver Gavin on the GT2 pole for Corvette Racing with 3m59.435s, just ahead of teammate Jan Magnussen.
