Some race events are listed as "Boss Race" in the event description. 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). When you win a Boss car, it will appear in the Pocket Garage, and you can race it in any game event.
When considering buying a car, do not buy any of the cars that are used as Boss cars. If you buy one, you will end up having two of the same car. Your garage can only hold 20 cars, and there are 24 cars total. The four Boss cars have their own separate garage and do not take up any of the twenty slots. You cannot get 100% completion if you buy any of the cars used as Boss cars.
Successfully complete the last race of a set with a gold medal to unlock bonus parts.
Before hitting a wall, press R1 to help avoid losing control.
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. Even if the timer runs out, your car will keep going enough without the gas and may pass the gate. If so, the timer will start again and your nitrous tank will be refilled, allowing you to continue with the race.
You can earn all the upgrade points in an event by winning it on the Bronze and Silver difficulty settings. However, to get all of the driver points you must win all of the races on the Gold difficulty setting. Check the "Driver Status" screen in "My Underground" to see your current driver points and driver rank. Maxing out your driver rank will unlock secret bonuses.
After getting the RX-7, put the following upgrade parts on the car to obtain maximum speed: Aeromax spoiler, Beast Carbon Fiber hood, Gills roof scoop, and Max 1 body kit. Also, make sure you have all of the performance upgrades unlocked and ready to install. You can get over 210 mph with this setup and win a race by 42 seconds.
If you are having trouble figuring out which cars to use for what event, cars with high top speeds/acceleration are good for drag races; cars with good controls/handling are best for drifting; and cars with a balance of the three are good for normal racing.
On the nitrous run levels, let off the gas through tight turns. Otherwise, you will hit the wall and flip your car.
While driving, hit a turn too hard to fly up and over the railing. There is an invisible wall that you can ride. If you ride it correctly, you can land back on your wheels.
On the Bayside Run course, there are doors that you can go through without them moving. Drive over 175 mph and have NOS on when you are about to hit the doors. You will disappear and go through it to the other side without moving the wall. When you enter the sidewalk sale area, the right front door does not seem to work but this glitch can be done with all others.
