IROC XXX

IROC XXX was the 30th season of the Crown Royal International Race of Champions, which began on Friday, February 17, 2006 at Daytona International Speedway.

The all-star roster included thirteen drivers (in twelve cars) from seven premier racing series.

Tony Stewart consistently ran up front and won two races to win the championship, ahead of the equally consistent Matt Kenseth by 12 points.

As with the past two seasons, the drivers used their car colors and numbers from their native series (when feasible).

Due to a conflict with the NASCAR Busch Series race at Memphis International Raceway in October, Edwards withdrew from IROC and was replaced by Ryan Newman.
