Steve King, a sprint car driver from Jetmore, Kan., died Thursday of head injuries suffered in a wreck during a preliminary feature race on Wednesday.
King, 33, collided with the Turn 3 fence after something broke on his car, officials said.
"The danger is when you go head-on into the wall," Capitani said. "If it's a glancing blow, it kicks you out. That danger comes at the midpoints of the turns, so we're going to take a look at it."
