The 1991 Camaro marked the return of the Z28, missing from the Camaro lineup since 1988. The fast ride promised by the Camaro may be a relief for its passengers, none of whom seemed to find the 1991 model to be of acceptable comfort. Performance and acceleration are off-the-charts for this model, but passenger comfort, cargo room, and gas efficiency lag far behind. Of course, Camaro lovers love them for the thrill of the ride, not the thrill of conversation over the typically loud engine. Listening to the V8 roar can quickly cover up any whines of discomfort from one's person. There is another very rare option for the 1991. Well it really started in 1988, and did not start to catch on very well until 1989 and up. In 1991 in fact only 478 units (confirmed by GM)produced. It was/is known as the 1LE pachage. Here is what the 1991 version consisted of.Chevrolet built 478 Z28 Coupes with "1LE" equipment for 1991. As in 1989 and 1990, Ordering the RPO G80 Limited-slip rear axle & G92 RPO G92 triggered the build. RPO G92 required one of two engine combinations, the 305ci LB9 V8 with 5-speed manual, or the 350ci B2L V8 with 4-speed automatic transmission. When ordered with air condition�­ing, RPO G92 ($466) included engine oil cooler, 4-wheel disc brakes (except for a brief period when 4-wheel discs were deleted with a $287 credit), and dual-converter exhaust. When ordered without air condi�­tioning, RPO G92 ($675) added heavy-duty front brakes, aluminum driveshaft and spare wheel, special shocks and fuel pickup, and gas tank baffle. Fog lamps were deleted for weight savings and improved cooling. I will be posting a new forum for this package in a few days. Enjoy :) Terry
