Yup, there was an RS for that year:

As the oil crisis caused rising gas prices, a lighter 6 cylinder engine (V6) was used to replace the aging 250-cid straight -6 (I-6 otherwise known as the "Inline-6"). A 350 cid V8 was the standard engine in the Z28, but optional in others. With the Increase of horsepower to 190, meant the return of the cowl-induction hood. This was big news for the 1980 Z28.

The attractive Rally Sport option, now effectively only a paint treatment, was in its final year of this Generation Camaro.

Camaro entered 1980 wearing a new grille with (tighter crosshatch pattern and offering a revised engine selection. A lighter, more economical 3.8-liter (229-cid) V6 rated at 115-hp replaced the old familiar 250-cid I-6 as the standard engine. Camaro's sold in California also had a base 3.8-liter V6, but it was Buick's 231-cid engine. There was also a new 4.4-liter (267-cid) V8 option with a 120-hp rating, plus a 305-cid 155-hp V8 Camaro's with automatic transmission had a new torque converter clutch to eliminate slippage.

The grille used on the standard Camaro Sport Coupe had an emblem in the upper corner.

Berlinetta's had wire wheel covers as standard equipment.

Chevrolet billed the 1980 Z28 as "the maximum Camaro!" It had a new rear-facing functional hood scoop facing with an electrically activated flap that opened when the gas pedal was pounded on. Also available was the RS (Rally Sport) package with a rear spoiler, a sport suspension, black rocker panels, a black grille, black head-amp bezels, bright reveal moldings, sport mirrors and color-keyed Rally wheels.
