We will have only 2 teams per Tier and winning your "Tier Battle" will now mean beating your rival. If you beat your rival at the end of the season you go in the upper Tier. You you fail, you go down. Tier1 still provides 9Aero 9Eng and Tier5 provides 1Aero 1Eng, meaning that we could see a Tier2 team winning the championship with a 7Aero 7Eng car.
Tier1 - 9A 9E
Tier2 - 7A 7E
Tier3 - 5A 5E
Tier4 - 3A 3E
Tier5 - 1A 1E
Sponsors will definitely be deleted as your income will now be : Have you beat your rival during this race ? Yes +1, No =0. Plus 1PP for finishing the race, exactly as it is today.
