Contracts should be the same as staff variable contracts. Paying 500* for 30 days means 3000* for a full team for a month of racing. A season lasts 5 days and a Cup last 3 days, there should be contract lengths similar to these challenges available. Why not have 500* for 30d, 270* for 14d, 150* for 7d and 100* for 5d..It means a more balanced team available to race with.
