My apologies, I didn't mean that in a derogative way. More along the lines of we've talked about it a number of times and the consensus that we've reached is that it can be done in the R390 Race car, the Toyota Gt-one and the 787B. With the R390 running the best chance as it is more stable and controllable than the GT-one. The 787B doesn't have the gearing manipulation that the other two have to take full advantage of it's power.
Take some time, do some testing and give it a shot. Remember you only have to win 7 races, and qualify on the pole in 1 race. You can skip two races and still win with a margin of points.
Keep a set of T6s to run for on the track you qualify at. Then run T2's at all the other tracks.
Pit stops and top speed are where you'll win.
On further review of my notes, Test Course and Super Speedway are sure wins in the R390, as you've got loads more top end than the F1's.
So in reality, you really need to worry about 5 races. I'd skip Laguna and Cote. Laguna the F1's seem unrealistically hooked up. Cote is really long and your oil won't be fresh. I'd qualify at Seattle (but that's only me and I hate that track).
Tokyo R246 is a track where you can take advantage of your Speed. Along with Midfield. So the places to worry are at Rome, Grand Valley, and Apricot Hill.
Good Luck,
