Performance Rating

Upgrades are the best way to increase PR rating. However, Z class cars are banned from organized racing. However they are still able to be raced in unorganized racing. It is more recommended to upgrade a car to the top of a performance class, rather than completely maxing it out. For example, if a car reaches R 927 when maxed out, it will be beaten by cars that make it to the top of R class. However, if optimized for S 900, it would be much more competitive. Some cars, such as the Aspark Owl, come at the top of R class stock and a single upgrade would put it into Z class. Cars that come on top of a class stock are not as competitive, as if it is a car that has 600 horsepower, 350 torque, and weighs 2,000 pounds, and handles well, and comes at S 900, would not be faster than a 900 horsepower, 750 torque, 2,600 pound car that has more power to go faster through the corners, upgraded for S 900, coming at S 860 stock with the same specs as the other car but weighs 3,100 pounds.

The best car for classes B, A, S, and R are the Porsche Boxster Special Edition, specs:

B: 300 horsepower, 0-60 in 3.9 seconds, top speed of 162 mph

A: 550 horsepower, 0-60 in 3.0 seconds, top speed of 199 mph

S: 850 horsepower, 0-60 in 2.1 seconds, top speed of 241 mph

R: 1,567 horsepower, 0-60 in 1.65 seconds, top speed of 298.94 mph

And a fully upgraded 1,891 horsepower, to 60 in 1.32 seconds, and more than 330 mph top speed!
