This cheat only works when u are in the middle of the game 7-8 member
all you have to do is make your car fatser than it was in the beginning
now that u have made adjustments in your car its time to race not a blacklist member but to go back to blacklist member number 14 or 15's races now race them over and over again
and soon you will have money coming in by the thousands(because they should be easy to beat since your car is improved) winning the race will give you money
