Corvette C8 Z06, E-Ray & Grand Sport (2023-2027) Wheel Fitment Guide
The C8 Corvette Z06, E-Ray, Grand Sport and Grand Sport X share a 5×120 bolt pattern, a 66.9mm center bore, M14×1.5 60° conical lug nuts and factory 20×10 ET35 front / 21×13 ET40 rear wheels. This guide covers US model years 2023–2027, carbon-ceramic brake clearance and documented aftermarket setups, including the AWD E-Ray and Grand Sport X.
About this guide: Fitment data is compiled from owner builds on CorvetteForum and customer cars in wheel-maker fitment galleries, cross-checked against vendor fitment documentation. Use it as research for your build; ride height, tires, and alignment are still your installer's call.

Factory Wheel & Tire Configurations
Every car in this guide shares the hub hardware below, and every factory wheel, forged aluminum or carbon fiber, uses the same 20×10 ET35 front and 21×13 ET40 rear. That pair is the reference for every "mm out" figure in the aftermarket section below. The ZR1 and ZR1X use a 5×130 rear bolt pattern and are not covered.

Carbon Revolution builds the one-piece carbon wheels; the 21×13 rear was the widest wheel it had made. An owner who checked his rear wheel's stamp and asked a GM parts counter confirms the same ET35 / ET40 as the aluminum wheels. Carbon-wheel cars have longer studs and no stud recess, so spacers can't be used with these wheels.

Aftermarket Options
Aftermarket Wheel & Tire Configurations
Every car in this guide shares the same factory wheel position, so each card below is one aftermarket wheel size and each row on its ladder is one documented build at its effective offset, named by the car it was run on. The Front and Rear figures show how far that build's outer lip sits outside the factory 20×10 / 21×13 wheels.
Tap a setup to jump to its full card. Fit: Bolt-on = documented at stock ride height with no fender work reported · Lowered = documented on lowering springs or coilovers · Not reported = owners didn't say. Sources = owner builds (including customer cars in vendor galleries) and vendor fitment-guide setups documented on that card.
⚠️Platform-specific fitment notes — Corvette C8 Z06, E-Ray & Grand Sport
Front room is tight; the rear has the space.
Factory wheels sit noticeably deeper in the rear arch than the front. Owners on factory wheels usually leave the front alone or add 7–10mm and move the rear 15–20mm. Documented 20/21 fronts stay within about 12mm of stock, and the 19-inch track fronts at about 20mm out run track alignments with extra negative camber.
Carbon-ceramic brakes.
Carbon ceramics (398mm front / 390mm rear) are standard on the E-Ray and Grand Sport X and come with the Z06's Z07 package and the Grand Sport's Z52 Track package. Vendor documentation shows its 19-inch track wheels clearing both brake systems. Owners note that spacers don't sit flat on the carbon-ceramic rotor hats, and a dropped wheel can crack a rotor.
Lug nuts and carbon wheels.
Every car here uses M14×1.5 lug nuts with a 60° conical seat at 140 lb-ft. Cars ordered with factory carbon-fiber wheels have longer studs, so aftermarket wheels on those cars need open-ended lug nuts. FMB machines every set for 60° conical lug nuts, so your factory nuts or a conical set of the correct length fits.

The factory sizes moved outboard. Factory wheels sit deeper in the rear arch, so most rows push the rear about 15–20mm and the front 0–12mm. If your car is at stock height, look for the Stock height chip; spacer builds on factory wheels appear at their effective offset so the same position can be machined into the wheel.

A 19-inch track setup with a narrower rear than stock. The rear lip sits about 12mm out even though the wheel is ¾″ narrower, because the offset drops to ET18. Documented on R-compound tires and slicks with track alignments; a vendor guide pairs it with 275/35R19 and 325/30R19 tires.

The most documented 19-inch track size, with an inch wider front than stock. The front lip sits about 20mm out, so owners run track alignments with extra negative camber, and the vendor lists light modifications for some tire combinations. Most builds pair 295/30R19 fronts with 345/30R19 rears.

The 19×11 track front with a narrower 12.25-inch rear for 325-width tires. At ET30 the rear lip sits right at the factory position; the vendor's ET18 rear moves it about 12mm out. Both rows run track alignments, and the front sits about 20mm out like the 19×13.25 card.

Was this guide helpful?
Let us know how we did on Google.
Your feedback helps other owners find these free fitment guides. It takes about 30 seconds.
Built to the exact spec, not the closest one on a shelf. The setups above come from real C8 Corvette builds, and we CNC-machine every wheel to them directly. If a build needs a spacer to reach its offset, we machine that offset into the wheel instead.
Choose your setup.
This guide is built to give you what you need to pick a spec with confidence: documented C8 Corvette builds, tire sizes, and how each one fits. If you still have questions, we're happy to help before you order.
Engineering verification.
Our manufacturing partner confirms wheel specs, including bolt pattern, center bore, brake caliper clearance, backspacing and load rating.
Render approval.
You approve the design and final specs before we move forward with production.
Our fitment guarantee
Every set is guaranteed to mount on your C8 Corvette: 5×120 bolt pattern, bored to the 66.9mm hub, machined for 60° conical lug nuts, and made to the exact width and offset you approved.
How a setup sits on your car also depends on ride height, tires and alignment, so choose with your plans in mind.
What are the factory wheel and tire sizes on the C8 Z06, E-Ray and Grand Sport?
Every factory wheel is staggered at 20×10 ET35 front and 21×13 ET40 rear, on 275/30ZR20 and 345/25ZR21 tires. The Z06 comes on the forged Spider design, the E-Ray on a forged 5-spoke and the 2027 Grand Sport and Grand Sport X on a forged 10-spoke. Carbon-fiber wheels in the same sizes and offsets are optional.
What are the bolt pattern, center bore, lug nut and torque specs?
All of these cars use a 5×120 bolt pattern, a 66.9mm center bore and M14×1.5 lug nuts with a 60° conical seat, torqued to 140 lb-ft (190 Nm). The earlier C5, C6 and C7 Corvettes use 5×4.75 (5×120.65), so older Corvette wheels don't carry over. Carbon-wheel cars have longer studs and need open-ended nuts with aftermarket wheels.
What aftermarket wheel sizes fit at stock ride height?
At stock height, owners document the factory 20×10 / 21×13 sizes at about ET27 front and ET22 rear on 275/30R20 and 345/25R21 tires, which sits about 8mm out at the front and 18mm out at the rear. One owner runs ET28 / ET20 at stock height on 7mm and 20mm spacers. The 19-inch setups here are track builds.
What's the difference between flush and aggressive fitment, and how do I read the offset ladder?
Each card is one wheel size and each row is one documented build at its effective offset, named by the car it was run on. The Front and Rear figures show how far the outer lip sits outside the factory 20×10 ET35 / 21×13 ET40 wheels. Most street builds move the rear 15–20mm; the roughly 20mm 19-inch fronts are the aggressive end.
Do aftermarket wheels clear the carbon-ceramic brakes?
Carbon ceramics are standard on the E-Ray and Grand Sport X and optional on the Z06 and Grand Sport. Vendor documentation shows its 19-inch track wheels clearing both the iron and carbon-ceramic systems, and owners run 20/21 aftermarket wheels on carbon-ceramic cars. Spoke profile matters as much as diameter, so tell us your brakes when you order.
Can I run a square setup on a C8 Z06 or E-Ray?
We haven't found a documented square build; Chevrolet only offers staggered wheels on these cars, with a 13-inch rear against a 10-inch front. Even the 19-inch track setups documented here keep a wider rear. Running one width at both ends would mean a much narrower rear tire or a front that sits well past the fender, so we don't list one.
Can I run aftermarket staggered wheels on the AWD E-Ray or Grand Sport X?
Yes, E-Ray owners run both 20/21 and 19-inch track setups. Staggered configurations can produce front-to-rear rolling diameter mismatches that may stress the front-axle drive system over time. The factory 275/30R20 and 345/25R21 tires are the baseline; check any other combination against your owner manual before committing.
Should I use wheel spacers?
Spacers on factory wheels are common: 15–20mm in the rear, often with nothing up front, or 7–10mm at the front. Owners report 15mm rear spacers need the stud tips trimmed, front spacers need extended lug nuts, and spacers don't work with the carbon wheels. Spacer setups appear here at their effective offset, and FMB machines that offset into the wheel.
What are the best winter wheel options?
Chevrolet doesn't list a dedicated winter wheel for these cars. Michelin's Pilot Alpin winter tire comes in the factory 275/30R20 and 345/25R21 sizes, and keeping a cold-weather set at the factory 20×10 ET35 / 21×13 ET40 keeps overall diameters at stock, which matters on the AWD E-Ray and Grand Sport X.
Which cars and model years does this guide cover?
US-market C8 Corvette Z06 coupes and convertibles for model years 2023–2027, the E-Ray for 2024–2026, and the Grand Sport and Grand Sport X for 2027, which replaced the E-Ray. The ZR1 and ZR1X are not covered because they use a 5×130 rear bolt pattern, and the narrow-body Stingray has its own guide.
Will C8 Stingray or ZR1 wheels fit, and do these wheels fit a Stingray?
The C8 Stingray uses 19×8.5 ET52 / 20×11 ET64 wheels on the same 5×120 hub, but they sit far inside these wider fenders and may not clear the bigger widebody brakes. An owner who test-fit Z06 wheels on a Stingray found they stick out past its fenders. ZR1 fronts share the 5×120 pattern, but ZR1 rears are 5×130 and won't bolt on.
