Well. Yeah. I guess if you really need to save money, you could fire them or let the contracts run out. idk.
Then again. I don't understand how you can lose money in this. I know people I have raced against have, but it's not to hard to make money as long as you don't swap around drivers and staff all the time.
I jumped in a two driver league at the beginning and that cost me a lot of money. It's been a long road to recovery, but I'm almost back to where I need to be and have all the facilities I need to compete.
