1988 Chevrolet Camaro IROC Z 2dr Convertible

1988 Chevrolet Camaro IROC-Z Convertible â?" 5.7L TPI V8 with Performance Upgrades Why This Car Is Special The 1988 Chevrolet Camaro IROC-Z Convertible is one of the more difficult configurations to find in the third-generation Camaro market. Chevrolet did not build the IROC-Z convertible in-house. Instead, the conversion was performed by American Sunroof Corporation, better known as ASC, Inc., which had a contract with General Motors to handle open-top versions of the third-gen Camaro. ASC removed the factory roof structure, reinforced the body to compensate for the lost rigidity, and installed a folding soft top. The result was a factory-sanctioned convertible that carried a full GM warranty. These cars were more expensive than the coupe when new, sold in lower numbers, and have always commanded stronger collector interest.
