Free parts and mods
Go to a garage and start a race. Before selecting the
difficulty, go to your garage. Customize and repair all the cars
your money will allow. Exit the garage and start the race. Once
the race has begun, restart it. Your money will be returned, but
all the mods and parts will remain. Note: The car you accept the
race in cannot be modded for free. Also, the more money you have
the less you will have to repeat the glitch.
