she is not going to nascar
irl races like 14 weeks a year
nascar like 36 weeks.
she'll never win a race in nascar.
she might someday win a race in IRL.
she did this so she'd get a better contract next year for racing in IRL as her contract is up after this year.
She should stick with IRL since that is where her low weight gives an edge. IF she doesnt do well at nascar it could prove to be embarassing and ruin her carrer.
