hi guys,
i have a question and i hope you can help me!?
-Wich Le Mans winner owns the record in spending lowest overall time in the pitlane at the 24 hours?
-How much of this time (in %) was needed for changing tires?

i think it was a Porsche (maybe the GT1 in '98?) but i'm not sure.

hope you can help me and please excuse my bad english!
