This thread is intended as sort of an instructional guide to tuning cars in gt2. I will not be able to post the whole subject right away due to it's complexity. I will attepmt to cover everything that I have figured out about it in short manageable posts. If you have any questions or comments, please do not post them in this thread. I would like to keep it intact for printability when it's finshed. Instead, start a new thread with your question/ comment. Thanks and I hope you find this useful.
