_1990
The 1990 model year was only a half year of production. All 1990 Camaros were equipped with tinted glass, tilt steering column, intermittent wipers and halogen headlamps. Due to the termination of the Chevrolet IROC contract, no IROC-Z's were produced after 12/31/1989. Instead, the 1991 Camaros were introduced early during last half of the normal 1990 model year. 1990 IROC's and RS's are easily identifiable: 1990 was the first year for the updated interior which included drivers side airbag, redesigned instrument panel, yellow lettering on dash, rounded controls, etc. So 1990 IROC's are the only IROC's with the new interior. The 1990 RS's are the only RS's with the new interior and the older valances (before the new `scooped' side valances). The LB8 2.8 liter V-6 was replaced by an increased displacement 3.1 liter LH0 V-6. In 1990, the base engine for the IROC was finally the LB9 TPI 305 rather than the base LO3 V-8. However, G92 had to be specified now to get the better cam/230hp LB9 motor in the 5 speed LB9 IROC-Z. Previously, all 5 speed LB9 IROC-Z's got the higher output LB9. The IROC-Z convertible now came standard with 16 inch wheels and P245/50ZR-16 tires. The G80 limited slip differential became standard equipment on IROC-Z. 1990 Engines
