The narrow-body C7 Corvette Stingray and Stingray Z51 use a 5×4.75 (5×120.65) bolt pattern, a 70.3mm center bore, M12×1.5 60° conical lug nuts and factory ET56 front / ET79 rear wheels on 18/19 or 19/20 sizes. This guide covers US model years 2014–2019, rear fender clearance on wider wheels and base versus Z51 brakes.
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 Stingray shares the hub hardware below. The base 18/19 wheels and the Z51 19/20 wheels have the same 8.5-inch ET56 front and 10-inch ET79 rear widths and offsets, so every "mm out" figure below is measured against that one position. The widebody Grand Sport, Z06 and ZR1 have their own guide.

The Z51 wheel became standard on every Stingray for 2018, replacing the 18/19 base wheel. It keeps the base car's widths and offsets in larger diameters, on Michelin Pilot Super Sport run-flat tires. Finishes include Silver, Black and Chrome, plus satin black red-stripe and black yellow-stripe versions in later years.

The standard non-Z51 wheel through 2017, with taller-sidewall 245/40ZR18 and 285/35ZR19 tires. It shares the Z51 wheel's widths and offsets, so any Z51 wheel bolts on in the same position. Owners upgrading base cars to Z51 brakes report tight clearance under this 18-inch front, with some removing the Z51 pad weights to clear it.
Aftermarket Options
Aftermarket Wheel & Tire Configurations
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 8.5-inch ET56 front and 10-inch ET79 rear 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.
The narrow-body rear is tight. Owners running 20×11 rears report clean fitment at ET76–78 and fender-lip rubbing over bumps at ET73 with a 305/30R20 tire. Wider wheels need high rear offsets: the documented 12-inch rear runs ET85. Grand Sport and Z06 wheels sit well outside these fenders and don't fit.
Base and Z51 brakes differ.
Base cars use 320mm front rotors and Z51 cars 345mm. Owners report tight clearance between the factory 18-inch base front and Z51 calipers. The 18-inch aftermarket fronts here are documented on Stingray and Z51 cars; tell us your brake package, and any upgrade, when you order so caliper clearance is checked.
Lug nuts and hub.
Every C7 Stingray uses M12×1.5 lug nuts with a 60° conical seat at 100 lb-ft, on a 5×4.75 bolt pattern and a 70.3mm hub. C8 wheels use 5×120 and won't fit. FMB machines every set for 60° conical lug nuts, so your factory nuts or a conical set of the correct length fits.

A square option for owners who want to rotate tires front to rear. The same 18×10 ET58 wheel goes on all four corners, which puts the front about 17mm out and the rear about 21mm out of the factory position. Vendor documentation notes a square car gives up some rear grip compared with staggered.

The factory Z51 sizes, for owners who want a forged wheel that sits exactly where the stock one does, or a few millimetres further out. The ET50 / ET75 build moves the front about 6mm and the rear about 4mm. Factory tire sizes carry over. Neither source reported ride height or rubbing, so the fit column reads not reported.

The most common street upgrade: a half-inch wider front and an inch wider rear on 19/20 wheels. The rear offset matters most. If you want no rubbing, start from the top row; one non-Z51 owner on 20×11 ET73 rears with 305/30R20 tires reports the rear catching the fender lip over bumps.

An 18/19 setup that opens up far more tire choices than the factory 19/20, including R-compounds. Owners use it for street driving and track days. The front sits about 17mm out, and vendor documentation lists it for factory suspension and alignment. Choose the ET78 rear if you want the most fender clearance.

An 18-inch rear in place of the 19, for the lowest wheel cost and a taller rear sidewall. Both documented cars run the same offsets, about 17mm out at each end. One is lowered on the factory height bolts. Check rear tire diameter against the factory size so the speedometer stays close.

A plus-one 20/21 setup for looks. The 12-inch rear uses a high ET85 offset to keep the tire inside the narrow-body fender, which still leaves the rear lip about 19mm out. Low-profile tires cost ride quality. One owner build only, so treat it as a starting point.

A track setup with a two-inch-wider front. The ET83 rear sits about 15mm out, while the front moves about 29mm out, so plan on camber. The owner found the 305/30R19 rear clear and the taller 325/30R19 rubbing under track load, which makes rear tire height the limit here.

The vendor's hardcore track staggered setup: an 11-inch front for the widest front tire the narrow body takes. The front lip sits about 31mm out, so negative camber is required, and the vendor notes some liner contact at full lock on the most aggressive tires. Not a street setup.

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 C7 Stingray 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 C7 Stingray 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 C7 Stingray: 5×4.75 bolt pattern, bored to the 70.3mm 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 C7 Stingray and Z51?
Non-Z51 Stingrays from 2014–2017 use 18×8.5 ET56 fronts and 19×10 ET79 rears on 245/40ZR18 and 285/35ZR19 tires. The Z51, and every Stingray from 2018, uses 19×8.5 ET56 and 20×10 ET79 on 245/35ZR19 and 285/30ZR20. Both setups share the same widths and offsets, and the factory tires are Michelin Pilot Super Sport run-flats.
What are the bolt pattern, center bore, lug nut and torque specs?
The C7 Stingray uses a 5×4.75 (5×120.65) bolt pattern, a 70.3mm center bore and M12×1.5 lug nuts with a 60° conical seat, torqued to 100 lb-ft (136 Nm). The C8 moved to 5×120 and a 66.9mm bore, so C8 wheels don't carry over. FMB machines every set for 60° conical lug nuts.
What aftermarket wheel sizes fit at stock ride height?
Owners document 18×10 ET58 / 19×11 ET78 at stock height, about 17mm out front and 14mm out rear, and a non-Z51 car at factory height on 19×9.5 ET56 / 20×11 ET73. A 2014 Z51 on 19×9.5 ET57 / 20×11 ET78 with 265/35R19 and 305/30R20 tires reports it fits very well. Higher rear offsets give the most fender clearance.
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 8.5-inch ET56 front and 10-inch ET79 rear. Street setups move about 12–19mm; the wide track fronts at 29–36mm out are the aggressive end.
Will 18-inch wheels clear my brakes?
Base cars have 320mm front rotors and Z51 cars 345mm. Owners report tight clearance between the factory 18-inch base wheel and Z51 front calipers, but the aftermarket 18-inch fronts on this page are documented on Stingray and Z51 cars. Clearance depends on spoke shape as much as diameter, so tell us your brakes and our manufacturing partner checks it.
Can I run a square setup on a C7 Stingray?
Yes, mostly for track use. Vendor documentation lists 18×10 ET58 all around on stock suspension and 18×11 with at least −2° of front camber. One gallery car runs 18×11 on all four with widebody front spats. Square setups let you rotate tires but give up some rear grip, so staggered setups remain the common street choice.
Do Grand Sport or Z06 wheels fit a Stingray?
They bolt on, sharing the 5×4.75 pattern and 70.3mm bore, but their 19×10 ET43 / 20×12 ET59 sizes put the front lip about 32mm and the rear about 45mm outside the Stingray wheels. Owners report they stick out and rub on the narrow body. See the C7 Grand Sport, Z06 and ZR1 guide for widebody setups.
Should I use wheel spacers?
Spacers are rare on the narrow-body builds documented here because the rear offset is already tight. One track car runs a 5mm front spacer with 18×11 wheels and widebody front spats. Spacer setups appear at their effective offset, and FMB machines that offset into the wheel, so no spacer is needed.
What are the best winter wheel options?
We didn't find a dedicated factory winter wheel for these cars. Owners use the 18/19 base wheels or the factory 19/20 sizes for cold-weather tires because they keep factory clearances. On a Z51 car, check that an 18-inch front clears the larger front brakes before ordering a winter set.
Which cars and model years does this guide cover, and how do I tell base from Z51?
US-market C7 Corvette Stingray coupes and convertibles for model years 2014–2019, with or without the Z51 package. The window sticker or the car's RPO list confirms the Z51 package. Before 2018, non-Z51 cars usually came on 18/19 wheels; from 2018, every Stingray came on 19/20 wheels.
Do C6 or C8 Corvette wheels fit a C7 Stingray?
C6 base wheels share the 5×4.75 pattern, 70.3mm bore and the same 8.5-inch ET56 / 10-inch ET79 sizes, so owners treat them as the same fitment, subject to brake clearance on Z51 cars. C8 wheels use 5×120 and a 66.9mm bore, so they won't bolt on.
