The 2027 model year brings some pretty significant updates to the mid-engined Corvette lineup, including the long-awaited arrival of the new Corvette Grand Sport. As expected, the new C8 Grand Sport offers a new special performance package aimed at improving the sports car’s handling, braking and track capabilities. The question is – how does it compare to the Z51 performance package offered on the C8 Stingray? Now, GM Authority is taking a closer look.
Let’s start with the C8 Stingray’s Z51 Performance Package, which raises the price to $78,890 for the 1LT Coupe (compared to $73,495 without it). The Z51 package combines a comprehensive set of hardware upgrades, with core upgrades such as Z51 performance brakes (RPO code J55) and Z51 performance suspension (RPO code FE3), paired with a shorter rear axle ratio of 5.56 (RPO code G0K), the latter a new addition for the 2027 model year. The Z51 package also adds an electronic limited-slip differential (RPO code G96), while aerodynamic upgrades consist of a Z51 rear spoiler (code RPO T0A) and front splitter.
Finishing touches include the ever-popular Michelin Pilot Sport 5 S (code RPO QTU) tires, measuring 245/35ZR19 at the front and 305/30ZR20 at the rear. A heavy-duty cooling system (RPO code V08) completes the package.
Stepping up to the Corvette Grand Sport introduces higher performance underpinnings, reflected in the $88,495 starting price for the 1LT coupe. From there, buyers can choose between two different Z52 packages. The first is the Z52 Sport Performance Package (RPO code FEB), which raises the vehicle’s price to $91,995 while expanding the Grand Sport’s capabilities with upgraded stopping hardware via six-piston front brakes and four-piston rear brakes (RPO code J56). It also adds a more aggressive tire setup.
For buyers who want maximum performance, the Z52 Track Performance Package (code RPO FEY) pushes the boundaries even further, bringing the total vehicle price to $109,190. This package adds carbon ceramic brakes (RPO code J57) with Dark Gray Metallic calipers (RPO J6D), as well as Michelin Pilot Sport Cup 2 R tires (RPO code XFS).
Additional upgrades include a quad center-exit exhaust (RPO code WUB) and a Carbon Flash-painted carbon fiber aero package (RPO code T0F), complemented by carbon fiber ground effects (RPO code CFZ). The combination of these upgrades significantly improves high-speed stability, braking durability and track-focused performance, positioning the Grand Sport as a serious upgrade from the Stingray.
Finally, there’s the Corvette Grand Sport X, which is priced from $112,195 for the 1LT Coupe. The optional ZER Performance Package, priced at $500 (bringing the total vehicle price to $112,695), is expected to have relatively modest coverage, at least compared to the upgrades mentioned above. While official details are limited, the package is expected to reflect the ZER setup offered for the C8 E-Ray, which includes high-performance tires (RPO code XFR) measuring 275/30ZR20 front and 345/25ZR21 rear, along with a ZER-tuned suspension featuring Magnetic Selective Ride Control (RPO code FED).
