In general, performance parts aim to improve vehicles' acceleration, handling and braking.

The aftermarket includes almost every performance part you can imagine that will improve the power or handling of a car. These parts include anything from high-performance wheels that reduce the car's weight to performance engines that have significantly more power than the stock engine.

Performance parts are replacement or enhancement auto parts engineered to improve a car's acceleration, braking, or handling. Enthusiasts frequently replace stock parts with aftermarket parts to improve the car's performance.
