Yes, i searched but did not find...
The reason I ask is that I find it fun to make updated versions of cars in GT4 and compare it to the original... the car in questions being the DB9. Aston Martin recently created a sports pack (and now a true 6-Speed manual as well!) for the DB9 which includes 68% firmer dampers in front, and 64% firmer dampers in back... basically I have a lot of hard facts about what was changed over when the sport pack was created... but i have no baseline to start with, and don't know what the stock settings are.
Thanks for the insight though, and btw I read both of your tuning guides front to back... Top notch stuff!
