B spec - every 5 level, you're allowed to create 1 new driver.

*Note B spec level, not your driver level

no no , I mean the AI driver . . hehe

if you keep using 1 driver, the driver lvl will overtake B spec lvl

example:
my AI driver lvl34 but my B spec lvl only 33

Finally

I guess you're using FGT

I usually used the default setup for this race, sometimes set the top speed to 330km/h.
Even with the default setup, I can lapped the 2nd place about 110+ laps.

It's gonna be the ride of your life.
You'll be taking corners with speed that you never imagine possible

Its does 400km/h with ease like FGT does 300 km/h without breaking a sweat

merry christmas
