 2nd: Is the racer affiliated with any racing teams or sponsors?
It's simple the higher a racer places in the finsh the higher purse, or prize money, is. Also if a racer has any affiliations that can bring in a few extra bucks. Sponsors are a major way to get the healthy check in your mail.
While a racer is still in the amatuer circuit they'll win only a few thousand dollars for first. A pro racer will win tens of thousands of dollars just for coming in last.
When a racer gets a team there average salary is $7500 a month. Almost $90,000 a year.
