REV LIMIT The balancing system using air restrictors has been replaced with a rev limiting system. The rev limit can be altered at various points throughout the season and applies to each individual manufacturer.
CONCESSIONS A concession points system will be introduced to restrict engine development of the fastest machines. At certain stages in the season teams that have achieved fewer concession points will be allowed to introduce updated concession parts. As a secondary benefit, the private teams will get access to cost capped engine parts to help them reach performance levels similar to the factory supported teams.
FRONT AND REAR SUSPENSIONS AND APPROVED ENGINE PARTS Price caps and approval process have been applied to several key frame, suspension and engine parts. These are called approved parts.
