Special Performance Package (coupe) (ZR1)
Extensive performance upgrades to the base model Corvette.
The ZR1 option included unique bodywork (doors, rear quarters, rocker panels, rear fascia, and rear upper panel.
ZR1 optioned Corvettes were fitted with special Goodyear Z-rated P315/35ZR17 tires that were mated to 11-inch wide rear rims.
The ZR1 option included a number of other RPO’s (normally listed separately) including: Power Passenger Seats (AC1), Power Driver Seats (AC3), Sports Seats, Leather (AQ9), Selective Ride and Handling, electronic ( FX3), Stereo System with CD, Delco Bose (U1F), and Low Tire Pressure Warning Indicators (UJ6). Additionally, the six-speed manual transmission (MN6) was required.
The ZR1 was also fitted with a special LT5 engine (that was unique and limited to the ZR1 coupe.) The LT5 engine was designed with the same V-8 configuration and 4.4 inch bore spacing as the standard L98 engine, but was otherwise an all new Chevrolet/Lotus design with four overhead camshafts and 32 valves..
Despite extensive use of aluminum, the complexity of the LT5 engine caused it to weigh just under 40 pounds more than the base model iron-block engine.
The LT5 Engine produced 375 horsepower but still managed to avoid the EPA’s gas guzzler tax.
The LT5 Engines were assembled by Mercury Marine in Stillwater, Oklahoma, and were then shipped to the Corvette plant in Bowling Green Kentucky for ZR1 Corvette assembly.
Chevrolet service departments returned LT5 engines to Mercury Marine for certain repairs. Customers were given the choice of a replacement engine or return of their original engine, if repairable.
RPO K05 (Engine Block Heater) was not available when the ZR1 option was ordered.
The ZR1 option was only available in the coupe bodystyle.
Low Tire Pressure Warning Indicator (UJ6)
Low tire/air pressure monitoring and warning system.
Sensors strapped to each side of the inside of each wheel sent a radio signal to a instrument-panel receiver if pressure in any tire dropped below a preset limit.
This option was included as part of the ZR1 package.
Stereo System, Delco-Bose (UU8)
200 watt Delco Bose AM/FM stereo radio with cassette.
Stereo System with CD, Delco-Bose (U1F)
200 watt Delco Bose AM/FM stereo radio with compact disc player.
This option was included as part of the ZR1 package.
To discourage theft, the CD player required an electronic security code input after battery disconnect.
Luggage Rack (convertible) (V56)
Optional luggage rack that was mounted to the rear decklid of the Corvette convertible.

1990 Corvettes had improved ABS (Anti-Lock Braking System) and improved yaw control.
The RPO V01 Radiator and B4P Boost Fan were not optional in 1990 as both were unnecessary due to 1990’s more efficient, sloped radiator design.
6-Speed Manual Transmission (MN6)
An optional, no-cost, 6-speed manual transmission.
The six-speed manual transmission was designed jointly by ZF (Zahnradfabrik Friedrichshafen) and Chevrolet and was initially built by ZF in Germany.
A computer-aided gear selection feature bypassed second and third gears (and locked out fifth and sixth) for improved fuel economy when a series of low performance criteria were met.
California Emission Requirements (NN5)
Revised emission/exhaust components to meet California Emission standards

The RPO V01 Radiator and B4P Boost Fan were not optional in 1990 as both were unnecessary due to 1990’s more efficient, sloped radiator design.
