If you go to your user control panel
http://www.clubcobra.com/forums/usercp.php
You can now "Edit Vehichle Profile" there. You can add some specifics about your car/engine and then even add info about your drag racing times.
This information will then be displayed here:

Please let me know how it works out. By the way, if you don't enter in a quarter mile time, it will not show on the timeslips page.
