The RPO MN 6 manual transmission no-cost option for 1989 was a new 6-speed designed jointly by ZF (Zahnradfabrik Friedrichshafen) and Chevrolet built by ZF in Germany. A computer-aided gear selection (CAGS) feature bypassed second and third gears (and locked out fifth and sixth) for improved fuel economy in specific non-performance conditions.

The Corvette Challenge race series terminated at the end of the 1989 sixty Challenge cars with standard engines. Meanwhile, CPC Flint Engine built special, higher horsepower engines which were shipped to the Milford Proving Grounds for storage, then to Specialized Vehicles, Inc. (SVI), Troy, Michigan, where they were equalized for power output and sealed. Bowling Green sent thirty cars to Powell Development America, Wixom, Michigan, where the roll cages and safety equipment were installed and the engines from SVI were switched with the original engines. At the end of the season, Chevrolet returned the original numbers-matching engines to each racer

The RPO Z5 1 performance handing package option continued in 1989 available only in coupes with manual transmissions. A new suspension option, RPO FX3, permitted three variations of suspension control regulated by a console switch. It could be ordered only with RPO Z51. The RPO Z52 sport suspension (1987-1988) was not a 1989 option. However, through all 1989 Corvette with FX 3 were Z5 is, these had Z52 springs and stabilizers for a wider range of suspension control. The only exceptions were the sixty Corvettes built for the Challenge race series which had FX3 suspensions with Z51 springs and stabilizers.

The standard six-slot, 16x8.5-inch wheel introduced in 1988 was discontinued for 1989. The twelve-slot, 1 7x9.S-inch style included with 1 988~s Z51 and Z52 options became 1 989~s standard equipment wheel.

On April 19, 1989, Chevrolet advised dealers that the ZR-1 would be a 1990 model, not a late-release 1989. The reason cited was "insufficient availability of engines caused by additional development." About 100 1989 ZR-1 Corvettes were built for evaluation, testing, media preview and photography, but none were release for public sale.

Seats were restyled, but the three choices of cloth, optional leather, or optional sport leather continued. Due to weight and fuel economy factors, Chevrolet intentionally limited sales of the sport leather seats by making them only available exclusively with Z5 1 -optioned models during 1989. The manual top mechanism was simplified for 1989 convertibles.
