Speed races hint
The most tempting choice in this category would be the Pagani Zonda. It is fast, but is very difficult to keep in a straight line. Instead, select the Porsche 911 turbo or the Dodge Viper.
Suspension: Increase the Caster to keep the car on a straight line. Make the steering response stiffer.
Drivetrain - Keep the gears as they are or make them all some clicks taller.
Cam timing - Seven clicks to the right (advance) or two or three clicks to the left.
Start/End Boost - Five clicks to the right or max it out.
Nitrous Pressure/Flow Rate - In the middle or slight to the right. If you like speed drifting, max it out.
