A racing car is modified for use in motorsports competitions. Depending on the discipline and category, a racing car may be based on a street car or may have been modified specifically for racing.

Sports cars are characterized by being wider, longer and taller; many of these are specially modified to have better grip on the asphalt or to drift.

Types of racing cars
In circuit and rally racing, it is very common to use passenger cars and sports cars, both because the necessary modifications are few and economical, and because automobile brands can advertise their models for sale through successful campaigns in this type of racing. Each category has a technical regulation to restrict modifications, which is called homologation. The International Automobile Federation determines approvals that are used on all continents, but many categories use their own approvals.

Other types of racing cars are single-seaters and sports prototypes, which have a single seat and have very little to do with street cars. Single-seaters are extremely narrow to reduce the surface area of friction with the air, and almost always use spoilers to increase vertical downforce. Another variety of racing prototypes are the silhouettes, which have a body similar to that of a street car but whose mechanics are completely different.

Race settings
In almost all categories, teams have the possibility of modifying car characteristics to improve racing and adapt to the track and weather conditions:

Suspension and steering
Suspension springs and dampers can be stiffened or softened to improve cornering and bump performance.
The ground clearance and maximum suspension travel can be adjusted to modify the behavior on jumps, bumps and slopes.
Wheel camber and camber angles can be modified to induce oversteer or understeer.
The steering ratio and hardness can be altered, for example to improve precision in wide corners or to negotiate hairpins more easily. A racing car is modified for use in motorsport competitions.

The steering ratio and hardness can be altered, for example to improve precision in open corners or to negotiate hairpins more easily.
