Even if the timer runs out, your car will keep going enough without the gas and may pass the gate. In the Nitrous Run Race, if your time is about two to four seconds from expiring, aim the car at the gate and use all the nitrous remaining. Avoid losing controlīefore hitting a wall, press R1 to help avoid losing control. Successfully complete the last race of a set with a gold medal to unlock bonus parts. You cannot get 100% completion if you buy any of the cars used as Boss cars. The four Boss cars have their own separate garage and do not take up any of the twenty slots. Your garage can only hold 20 cars, and there are 24 cars total. If you buy one, you will end up having two of the same car. When considering buying a car, do not buy any of the cars that are used as Boss cars. When you win a Boss car, it will appear in the Pocket Garage, and you can race it in any game event. Win that event under the gold difficulty setting to be awarded that Boss's car (1969 Dodge Charger, Subaru Impreza WRX STi, Chevrolet Corvette Z06 and Nissan Skyline R34 GTR). Some race events are listed as 'Boss Race' in the event description.
