Setup tips are good to have as setting up your car is very time consuming. Things like negative df and ways to overcome the difficulties it causes are good to be shared. That said, in general, my opinion is that if we keep setup open then everyone should find their own setup. I agree with Scott that it's competitive sport and no one shouldn't feel offended if fastest guys don't want to share their setup. In situations where you are very far off the pace because of your poor setup then I'm pro helping a friend out. Seeing alien setups once in awhile helps getting ideas but it's not a big help for the future if you don't understand the basic principles of setting up each car. There are a lot of good setup guides out there but where we can help out each other is telling some oddidies that the sim might have when setting up a sim car to perfection. Also remember that a perfect setup for one driver might be far off from perfect to another driver.
Thanks for sharing your tips TechG.
