While a four-speed manual transmission allowed Trans Am drivers to maximize performance, a five-speed manual became the standard in 1983, offering even greater control. Additionally, automatic transmissions were upgraded to four-speed models, incorporating a lock-up torque converter for improved efficiency.
The 1983 Firebirds were designed with a slightly taller and wider frame, and the Trans Am's V-8 engines received a modest power boost. Both the Trans Am and S/E models surpassed the $10,300 price point. For enhanced comfort on long drives, Lear/Siegler multi-adjustable bucket seats with lumbar support and adjustable bolsters were available. A foldable split-back rear seat was also offered as an option across all models.
Base and S/E Firebirds received suspension upgrades, delivering a smoother ride and a more agile driving experience. The Trans Am models showcased a distinctive off-center power blister on the hood, complemented by a fresh-air induction system. Additional performance-focused features included front-fender air extractors, wheel-opening flares, a rear spoiler, turbo-cast aluminum wheels, and a specialized suspension system designed to emulate race-car handling.
Two exclusive Trans Am editions were introduced: a black Recaro model adorned with gold tape striping and gold-finished cast aluminum wheels, and a white/gray Daytona 500 25th Anniversary edition. The Recaro package was priced at $3,160 with the standard 305-cid (5.0-liter) V-8 engine and a five-speed manual transmission, or $3,610 when paired with the "Cross-Fire" V-8 engine and a mandatory automatic transmission.
