Don't forget to take a quick glance at the comments.

Okay and 1 more thing, how do i edit handling for a car i downloaded, i DL a avalanche and it flips so id like to know how to edit the handling it came with, you know how?, like where do i go into to do so

Yes,you can do so.Here:

As Dhruv said, just highlight ALL the lines in blue then replace the line you highlighted with custom handling lines, my recommendation, even though sgt.Kanyo's handling lines are the best out there, i would back up the handling.DAT all the same
