as far as using B-Spec mode to get easy money.... if you put it on b-spec and then hit R1 to view the map screen, you can hold L1 and hit right on d-pad to make the race 3x faster than 'real time'.... now the computer will auto-pit when needed but it will go back on 1x after the pit stop... so if u pay attention to it, you can re-set it on 3x= money fast as possible...... i personally have been doing the endurance races that way.... even still, the 3 mofo 24hr races will take 8hrs to do.... your welcome.
