Easier Speedtrap races:
Activate your Blocker/Brawler before the race. While racing and coming up towards a speed trap, stop your Blocker/Brawler. Your Blocker/Brawler will stop, crash the other cars, and drastically slow down their time. Remember that the peak Blocker/Brawler moment is just before the speed trap.

Easy money:
Once you have completed Career mode, set Samson as your wingman with Neville also in your crew. You can repeat any races you have already completed in which a wingman is used and recieve 750 for each race completed instead of the 500 without. This can also be used on first time races for maximum cash output.
