1986
A newly required Center High Mounted Stop Lamp (CHMSL) was installed on the Camaro. 1986 was the only year to see this attached to the hatchback glass on base model Sport Coupes, Z28s and IROC-Zs. In following years it was incorporated into the rear decklid spoiler, except for 1987 base models that did not have a spoiler. This was the final year for the L69 5.0 305 HO 4bbl option, of which 63 were built for racing as Canadian Player's cars and 11 for public sale, making a total of 74. The 2.8 L V6 was now the standard engine in the base model, replacing the 2.5 L I-4 model. The 305 TPI LB9 horsepower rating dropped from 215 hp (160 kW) to 190 hp (142 kW) in the IROC-Z models. All V8 engines received a new one-piece rear main seal.
