Instructions
Buy the Porsche 911 Carrera RS from the car store.
In the main menu, turn all of the assist options to "On." Specifically, you should make sure Stability Management, the Traction Control System and the Anti-lock Brake System are enabled.
In the car tuning menu, make the following modifications to the Porsche. Change your "Tires Front" rating to 15 and your "Tires Rear" rating to 26. Set your "Front Springs" to 280 and your "Rear Springs" to 610. Finally, set your ride height to the highest possible level.
Choose a straight and easy race track and start the race.
Hold down the acceleration button. As you accelerate, rapidly press the brake button. Once you get to around 30 mph, your car should begin to wheelie.
