Downforce and drag

[Christian_C]

Here's a question for you: Is the benefit of downforce worth the extra drag or is it more effective to run low downforce and low drag? On an average track such as suzuka or the like?

In GT4, no matter how high you set the downforce, the drag never increased and never affected the top speed. Is it the same for GT5? Yes, I know I could test it myself, but I ask for a broader consensus. I will test this myself later.
