Callaway Forged C8 Corvette Wheels
Now in production
We are pleased to offer a true, fully-forged wheel in a refreshed nine-spoke design to complement the C8’s styling and which is engineered to improve performance by removing over 26 lbs (12 kg) of rotational mass compared to the original equipment.
The forged aluminum construction offers greater strength at significantly less mass, offering peace-of-mind against typical cast-wheel construction being prone to damage over poor road surfaces. The material properties of the forged alloy allow mass optimization in the design process by way of FEM (Finite Element Modeling) which results in a wheel set 23% lighter than the OE cast wheels. (19% front, 26% rear), despite their increased width, which is 0.5” over original. Offset is slightly reduced for a flush appearance and increased track width.
Reducing unsprung mass and rotational inertia offers many vehicle performance benefits as less energy is required to accelerate, change direction, and decelerate the wheels. The suspension performance is also improved as it has less work to do to maintain tire contact patch to the road surface. This means that driver inputs are more efficiently communicated to the tires: acceleration, steering inputs and braking. They utilize the same Michelin Pilot Sport 4S (ZP) or all-season OE tire fitments and compounds developed for the C8.
Callaway designers have always preferred odd-numbered spoke designs to convey a proper visual and mechanical balance; while thin spokes promote brake-cooling airflow, and are easy to clean. A variety of finishes are offered: satin black painted, gloss titanium painted, matte bronze painted, as well as two premium finishes: Black Chrome PVD and Ceramic Polished: a machine-automated polishing that is protected by a clear-coating which does not detract from the brilliance of the polished alloy. All finishes carry a 3-year warranty.
Carbon fiber center caps and lug nuts are included with each wheel. Select either bright chrome or black chrome PVD lug nuts when ordering. Optional wheel lock sets are also available in bright chrome or black chrome PVD.
These new wheels have passed performance testing per TÜV and ISO standards for fatigue bending, impact and rolling performance with exceptional results.

First Phase Callaway C8 being finalized for production
Double-D exhaust with new lower fascia panel
Callaway designs a 5th generation of its signature “Double-D” exhaust system, featuring a new iteration of the Single-Acoustic Chamber (SAC) originally developed for the Callaway C12 and later C7 Corvettes. Creating a unique sound signature, multiple baffled chambers inside a single canister are tuned to offer improved flow characteristics and frequency cancellation to eliminate in-cabin resonances, while offering a refined exhaust note. The center-exit Tips offer a balanced, unique appearance, and a new carbon fiber surrounding panel will allow for cooling airflow around the muffler, which is inherently thermally-challenged in a mid-engine configuration. Prototype testing and development in progress… stay “tuned”.
Callaway/O.Z. Racing Forged 9-spoke wheels
Finally, a fully-forged wheel produced in collaboration with O.Z. Racing, one of the world’s leading wheel manufacturers, supplying Formula 1, World Rally, and all levels of sportscar racing worldwide. Callaway and O.Z. have been working together on road car and motorsport applications for 30 years, including the championship-winning Callaway C7 GT3-R.
The fully-forged wheel is configured in a revised 9-spoke design to complement the C8’s new styling. The wheels are currently undergoing FEM and weight optimization with testing to exceed TüV and JWL standards commencing shortly. We expect the wheels to provide considerable weight savings over the OE offerings, which will yield dynamic handling benefits due to unsprung and rotating mass reduction. While they will be slightly wider than OE, will still utilize the phenomenal Michelin Pilot Sport 4S (ZP) OE fitments and compounds developed for the C8. Offset will be slightly reduced for a flush appearance and increased track width.
The forged/HLT® construction offers greater strength and stiffness at significantly less weight. Offering peace of mind against typical cast-wheel construction being prone to damage over poor road surfaces. A variety of finishes will be offered, including a brilliant ‘ceramic polished’ finish with a clear protective coating that does not detract from the brilliance of the polished alloy. Further aerodynamic and styling features will be announced in the upcoming months, while Callaway engineers are working on developing powertrain offerings as well. A line of track day-specific improvements will also be developed.
