The Camaro IROC-Z Sport Equipment package arrived for the 1985 model year as an option added to the Z28. The model was named for the International Race of Champions, in which the Camaro was the official car used by every driver. For the IROC-Z road car, the Camaro was lowered and fitted with sport suspension, stiffer steering, fog lights and unique graphics. The RPO B4Z improved handling package delivered .92g, and 0-60 mph came up in 7 seconds.
