Cheat IT

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 car(s), 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.
