Jeffy is right, there isn't a 'magical' setup. I have about 4 that will run the same laptimes and thats because I have had a ton of practice on my racing line. You may have to tweak your r2 gearing a little bit, but just work on your line.
Maybe we need to move the starting line back to the other start/finish line. Maybe it will get people spread out a bit more before the bend. But when you get into that Chaos draft in the front it is such a blast to race in.
Drafting on this track with r2 tires, the only problem spot is turn 3, so guess what you do in turn 3 when you can't run the ideal line? You change your line up till you can...
And that is racing. A full load of fuel your going to go slower then with less fuel. Depends on how you or your team wants to do the race. I have yet to run 100% with r2's but im pretty sure I can as a few others run sub 38's with 100% fuel on r2's. Under a green flag pit stop if your in and out of the pits in under 38 seconds and back up to full speed im pretty sure you didnt refuel, change tires, and fix damage.
The leader does set the pace, but when your back in the back, you gotta watch who is in front of you. When you see the green flag on the screen then you can go.
Good ole goob he just talks shit in vent and lets me do the posting. Although im horrible at saying what I actually want to say. But hey I didn't know he made the pictures its pretty sweet.
