New Chevy Corvette C8 Stingray owners eager to get the most from their mid-engine sports car are encouraged to opt for the Z51 Performance Package, which adds in a host of go-faster bits that take the C8 Stingray to even-greater levels of performance. Critically, the package may speed up delivery as well, as GM Authority has learned that non-Z51 Corvette Stingray units are currently under constraint.
According to GM Authority sources, units of the Chevy Corvette C8 Stingray not equipped with the Z51 package are currently under constraint due to a supply issue with the Mechanical limited-slip differential (RPO code G0J). The constraint applies to both 2022- and 2023-model-year vehicles.
As a reminder, the Z51 Performance Package includes an Electronic Limited Slip Differential (eLSD, RPO code G96), which replaces the Mechanical limited-slip differential equipped by non-Z51 Corvette C8 Stingray units. The Electronic limited-slip differential is available and only included with the Z51 Performance Package, the latter of which is offered as an optional extra for all three C8 Stingray trim levels. As it stands, non-Z51 orders are currently limited to 375 units a week.
For those who may be unaware, the eLSD differs from the Mechanical LSD in a few crucial ways. Essentially, while the latter unit uses mechanical factors to control the clutch and locking force between the right and left wheels, an eLSD uses the onboard computer to control the lock-up between the two rear wheels via a bevy of data and other inputs, such as tire temperature. The electronic unit allows for a greater range of tuning and control for more confidence-inspiring feedback between the car and the driver, thus encouraging faster and faster lap times.
As a reminder, the Corvette C8 Stingray is equipped with the naturally aspirated 6.2L V8 LT2 gasoline engine just behind the cabin, which is rated at 490 horsepower and 465 pound-feet of torque. Under the body panels, the C8 rides on the GM Y2 platform, while production takes place at the GM Bowling Green plant in Kentucky.
