in my opinion if you want to set WR in the '92s car this is what you have to do, but if you just want the money just drive as long your lap time is under one min and 36 sec because you'll still get 123k
the money you get depends of the time of your lap if it is > 1:39, it is 55k if it is 1:30 - 1:39, it is 99k if it is < 1:30, it is 123k and obviously, if it's invalid, 5k (this is not the complete information, this is just from what I experienced)
The money ALSO depends on what car you have for example the 2024 cars give you up to 74k per lap but the oldest cars give you up yo 123k per lap the older the car the most payment you get.
