Regulation Changes
In an attempt to reduce grip from specialised tires, D1GP now mandates the UN/ECE R117-02 international standard for wet performance, noise and rolling resistance. The grip reduction is implemented in order to decrease damaged cause by tires to the road surfaces and also to increase tire choices. The tires that will be used will undergo an inspection before being able to be use in competition. This rule change caused Linglong and Sailun to withdraw from the series because of an inability to provide tires with such specification.
Following dispute over a pit time limit in Autopolis, the time given to service a vehicle between rounds is limited to three minutes. An official will be observing the clock as the cars are being serviced.
