* It lacked the performance upgrades of the IROC-Z or the Z28. The RS typically came with a less powerful engine, usually a V6. While V8 options were possible, they weren't standard or common.
* Its focus was aesthetics. The RS package included features like sporty ground effects (side skirts, front and rear air dams), often a different grille, and usually special badging and wheels. It gave the Camaro a more aggressive look without the higher price and performance of the higher trim levels.
Think of it as a visually enhanced, more stylish base model Camaro. It offered the Camaro's shape and styling with a sportier look at a more affordable price point than the performance-oriented models.
