Learn to shift correctly. Rev your engine all the way into the green, but without going into the red. It is better to start before hitting green at your RPM instead of starting in the red. Tap the "Go" button as soon as the race lights turn red. Then, shift as soon as you get to green.
Wait until you have purchased new upgrades for your car before entering the race arena . The match making system pairs cars with similar values, without taking upgrades into consideration. Examine a car's value by looking in the top left corner before challenging it. Try to find cars with lower values than yours, as this usually means less horse power and an easier race to win. If the bet is too high and you are not confident that you will win, do not start that race. Only participate in races you are sure of winning.
When purchasing upgrades for your car, focus on those that are in the "Performance" category. Almost all the upgrades will increase the damage your engine takes. Purchase the Performance upgrades that do less damage than the others first. Upgrades to the intake system or the engine internals are recommended; the first levels are cheap and should be purchased as soon as possible. You will eventually reach a point where you will not be able to win any races without a NOS system. It is fairly expensive and requires a few upgrades in order to get the most out of it. Use the NOS in every race for an added bonus. The lighter the car, the faster it travels. Try to reduce its weight under the Chassis category. There are three upgrades you can purchase here. Get them before adding other performance enhancers to get a better boost. Unlike other upgrades, the Grip category allows you to immediately purchase the best tires. The best ones cost just over $500 and are worth it to get the best out of your car. Keep the aesthetic upgrades to a minimum while spending your money on more useful upgrades.
