1988 Chevy Camaro
The IROC-Z door decals were moved from the front of the doors to the rear. Z28 exterior badges were replaced with IROC-Z badges. The lower-body stripe was reversed changing from black on bottom with trim color above, to black on top with trim color below, now with a gap (of body color) between the two stripes. Newly available 1988 Chevrolet Camaro DX3 stripe delete option eliminated IROC-Z decals and stripes altogether.Sport Coupe took on the appearance of the defunct regular Z28 except for: `CAMARO' rather than `Z28' exterior badges; body colored headlight pockets rather than black; and gold or silver wheel center caps rather than black; the regular hood rather than the louvered hood; and the 1985-1987 IROC two tone lower body stripe rather than the four-color Z28 body stripe. This was the last year for the '88 Camaro Sport Coupe and was the only year for this particular appearance. Early in the year, 1988 Chevy Camaro -Sport Coupes came with a `shorty' rear wing rather than a spoiler. This ungainly addition was discontinued and replaced with the standard spoiler midyear. RS available in California, Texas, and Florida and with V-6 power only.Serpentine belt now on Camaro V-8's. Long-lived LG4 carbureted 305 replaced by the new LO3 throttle body injection 305. All Camaro TPI motors bumped up 5 hp due to slightly higher lift/longer duration cam profiles, additional valve seat angle, exhaust port/exhaust manifold changes.G92 (performance axle ratio) still available on IROC-Z convertible in 1988. G92 code was now available on the 350 (B2L) IROC-Z and now had to be specified to get 3.27 rear end (was standard in 1987) as a 2.77 rear was now standard on the 5.7 TPI. J65 rear disc brakes, G80 limited slip differential, and KC4 engine oil cooler were still required on all 5.7 and G92 cars.
