Danica Patrick has taken a big step towards confirming her final racing plans for this year's Daytona 500 and Indianapolis 500 after securing sponsorship from former partner GoDaddy.

Patrick raced with sponsorship from the web hosting giant during her time in IndyCar and the early part of her NASCAR career before the company ended its motorsport interests in 2015.

After losing her Stewart-Haas Racing NASCAR seat at the end of last season, Patrick announced in December she would make her final stock-car racing appearance at this year's Daytona 500, before making a return to the Indy 500 in May after seven years away.

Patrick admitted earlier this month she was finding it more difficult than expected to find seats for both races, but the signing of a deal with GoDaddy now acts as a major breakthrough.

"There's this great story," Patrick told the Associated Press.

"I left IndyCar with GoDaddy on my car, I started NASCAR with GoDaddy on my car, I'm most recognized as the GoDaddy green car and driver.

"So to finish up my career that way feels appropriate."

With this deal secured, Patrick has more leverage with which to find a seat for the Daytona 500 NASCAR race on February 18 before turning her focus to gaining a drive for the Indy 500 on May 27.
