ok guys, Just for you info
I have been able to succesfully go to the track with the Corvette_BOP 2009 AND 2010 on the server.
Be aware that their is a bug on the build 900+ that when you select a special upgrade package it does NOT show on the monitor... so even when I had the 2009, it still show the 2010 in the monitor.
an easy way to know wich class you have with the corvette is to look at your Max RPM...
2009: 6200
2010 default 6800, max 6900
It should fix this bug in the next build according to this:
