Just what in the holy hell are grid girls? Grid girls – otherwise known as race queens, pit babes, paddock girls , or umbrella girls – are extremely sexy women who are hired to keep their driver cool using an umbrella or other various methods all while wearing tight, revealing outfits that bear the racer’s sponsors. And, we all know, if you want to rock a skin tight, revealing outfit your body better be bonkers, buxom, and beautiful. That goes for the front AND the rear. So, while most fans check out the grill, we explore the tailpipe with this photo gallery of grid girls bumpers.
