Question: is an iroc z a z28?
Answer: The IROC-Z model of the Chevrolet Camaro made its first public appearance in 1985 as an add-on option to the Camaro Z-28, but its origin really comes from the world of car racing. ... IROC began in 1974 by racing Porsches, but the cost of maintaining them was prohibitive, so the series turned to the Chevy Camaro in 1975.
