A technical bulletin was issued last week to teams addressing an aerodynamic issue that NASCAR hopes will lead to improved side-by-side racing this week at Kentucky Speedway. But buried in the bulletin was a rule that took away teams' ability to use the sway bar as a suspension piece instead of an anti-roll bar as the car goes through the corner. That, along with an increased ground clearance on the side skirts of the Sprint Cup cars that is designed to take away downforce, take effect this week.
Earnhardt supposedly used this technique in winning his first race in four years a couple of weeks back.
