guys I dont know if any of you are already aware of this but there is defo a bug in this game. It hits mostly the ffb users but has also been know to affect ds3 users aswell. Have you ever been running practice laps and been getting, lets say 1 30 3xx in free run, then when the race starts you find it increasingly difficult to get 1 33 3xx? There is a thread to explain this bug further I recommend that you each read it from the 1st post, because A LOT of people are getting hit by this bug and quite a few leauges have had to disband because of it, im on my mobile, using the gtp app, so I dont know how to link to the actual thread, but I will try to find a way.
The thread is called GT5's dirty little secret, dont know if you can search threads, but if you can find it.
EDIT: If you search posts created by user, and search mgr it will come up with the thread.
