I tried marcandre187's setup, but unfortunately I found it to be no better than the "stock" setup. Results are pretty much the same:
Indianapolis: Super easy. Bob wins by half a lap or something.
Grand Valley: Taking it easy in the beginning to save tires and drops down to 9th or 10th place. Starts to pace up with 1 or 2 laps left, but is only able to reach 5th before the finish line (once I was lucky and got 3rd when 2 cars spun at the last chicane). Bob does have enough speed in the last laps, but when cars in front of him start burning rubber he doesn't try to pass, instead he slows down to watch the drift show from behind.
High Speed Ring: Gets into 1st within a few laps but loses 2 or 3 positions in the first corner every lap because of massive grip issues, and spins out completely in the same corner on the last lap, finishing 12th. If I try to pace down in the beginning and pace up in the second half of the race, he will fall down to 8th, and he just won't overtake a single car after I start to pace up.
Laguna Seca: Bob falls down to 8th in the beginning of the race. I then order him to pace up, but he will only manage to overtake 2 cars during the remainder of the race.
Daytona: I constantly keep spamming pace up. Bob gets into 1st quite fast, but then his wallriding and braking at the start/finish line causes him to drop down to 12th, and he will never get back into the pack again.
I don't get how getting into 1st on the road courses is even possible. Even if I pace up constantly from the start of the race, Bob simply won't overtake.
