The C8 generation Corvette is an evolutionary leap from the C7 generation Corvette. It brought a mid-engine layout to an American performance icon. The 2020+ Stingray is equipped with a 6.2L LT2 naturally aspirated V8 engine, producing up to 495 hp and 470 lb-ft of torque with the available performance exhaust. The Z06 is equipped with a 5.5L LT6 naturally aspirated V8 engine. The top ZR1X model boasts a 5.5L LT7 twin-turbocharged V8 engine paired with a front-mounted electric drive unit, delivering a combined output of 1,250 hp. The high horsepower and excellent handling of the C8 platform make it one of the most popular domestic sports cars on the market.
The C8 Corvette Stingray, including cars with the Z51 package, comes with one factory wheel size configuration from GM. 19-inch front and 20-inch rear wheels. It uses a bolt pattern of 5×120 mm and a center bore of 66.9 mm, with M14×1.5 wheel studs and conical lug seats. The base Stingray comes standard with ventilated brake rotors measuring 321×30 mm at the front and 339×26 mm at the rear. The Z51 package upgrades the rotors to 345×30 mm at the front and 350×27 mm at the rear. It is important to ensure your aftermarket wheels provide sufficient clearance for the brake rotors and calipers.

Forgelite's OEM+ fitment focuses on using Chevrolet's factory tire sizes to maintain the stock handling feel. We make the wheels to match the factory width or slightly increase the wheel width for owners intending to lower their C8 Corvette. The 19"/20" staggered sizing allows owners to upgrade their wheels without purchasing new tires. Option #2 increases the wheel width by 0.5 inches at both the front and rear. It allows you to run factory tires while keeping the option to upgrade to wider tires in the future. We will help you select the optimal wheel offsets based on your fitment goals to achieve a fender-flush fitment.

Forgelite's aggressive fitment allows you to run wider tires on a staggered 20"/21" setup for more traction and better braking performance. The 20"/21" setup can also significantly enhance the look of your Stingray, making it one of the most popular options for owners that are upgrading their wheels and tires.

Option#1 offers guaranteed fitment with no modifications or adjustments required to the car. It's a direct bolt-on fit with no rubbing issues. Option #2 is very aggressive for the Stingray. Although some manufacturers claim this fitment can be used without issues, we have found that minor rubbing may occur at the rear, depending on your exact tire selection and suspension setup. If you want to avoid rubbing entirely, Option#1 is the best choice.

The Chevrolet C8 Corvette Z06, E-Ray, ZR1, ZR1X, Grand Sport, and Grand Sport X share the same widebody dimensions, but their powertrains and brake options differ. The Z06 comes standard with iron rotors, with optional carbon-ceramic brakes available with the Z07 package. The ZR1 comes standard with J58 carbon-ceramic brakes, featuring 15.7-inch front rotors with 6-piston calipers and 15.4-inch rear rotors with 4-piston calipers. The ZTK package on the 2026-and-later ZR1 and standard on the ZR1X, feature J59 Alcon 10-piston front calipers and 6-piston rear calipers with 16.5-inch carbon cermaic rotors at both ends. The ZR1 and ZR1X also use different front and rear bolt patterns: 5×120 mm at the front and 5×130 mm at the rear. This means aftermarket rear wheels designed for the Z06 will not directly fit on a ZR1 or ZR1X. We engineer our wheels with the correct center bore, bolt pattern and brake clearance, including clearance for the J59 brakes, so Forgelite wheels are a direct bolt-on fit with no modifications, spacers or adapters needed. The Grand Sport offers standard iron rotors and optional carbon-ceramic brakes, while the Grand Sport X comes standard with carbon-ceramic brakes. It is crucial to have your wheels properly engineered and manufactured for your specific Corvette model.
For Z06, E-Ray, ZR1, ZR1X, Grand Sport and Grand Sport X models equipped with factory carbon-fiber wheels, the wheel studs are approximately 1" longer than those on cars with factory aluminum wheels. We can build our wheels to accommodate these extended studs allowing use factory close ended lug nuts.
The C8 Corvette Z06, E-Ray, ZR1, ZR1X, Grand Sport, and Grand Sport X come with one factory wheel size configuration from GM. The Z06, Grand Sport and Grand Sport X use a bolt pattern of 5×120 mm and a center bore of 66.9 mm, with M14×1.5 wheel studs and conical lug seats. The ZR1 and ZR1X use a bolt pattern of 5×120 mm at the front and 5×130 mm at the rear, with a center bore of 66.9 mm, M14×1.5 wheel studs and conical lug seats. The rear wheels for a ZR1/ZR1X will not fit on a Z06/Grand Sport/Grand Sport X due to different bolt pattern.

Forgelite's aggressive fitment focuses on using Chevrolet's factory tire sizes to maintain the stock handling feel. GM's factory wheel width and tire sizes are adequate for the car.

It's a direct bolt-on upgrade with no need for spacers or adapters. The factory 20"/21" staggered sizing allows owners to upgrade their wheels without purchasing new tires.
