Is there any requirement for configuration in wrc9fla World Rally Championship?

The car of the World Rally Championship is modified on the basis of the 4-cylinder 2.0-liter production car, and the WRC car must use the standard body of the production car. When using WRC, all parts of the mass-produced car body will be removed, leaving only the metal frame, and all spot welds will be re-welded.

In order to reduce the weight, all the redundant brackets and fixing plates of the car body should be removed, and at the same time, an anti-roll frame made of steel pipe should be installed. Most WRC racing cars can support the weight of 10 ordinary cars. The FIA requires all WRC engines to install a throttle with a size not larger than 34 mm at the air intake, and limit the power of the racing car to 300 HP.
