C5 Corvette fitment guide for the JDM enthusiast (narrow + widebody)
Today we’re looking at C5 wheel fitment. This isn’t going to be your typical fitment guide, this will be specifically for those who dig JDM styling–after all, the C5 is basically an RX-7 that comes pre-LS swapped. So, if you wear jean shorts with Filas, drink Pabst Blue Ribbon, and think this post should be a ‘rim’ fitment guide, this probably isn’t the one for you. On the flip side, if you like sleepy eye mods, stretched tires, and aggressive fitment, keep reading.
- This guide is specifically for the Fifth Generation Corvette, model years 1997-2004 (including all body styles: coupe, convertible, and FRC)
We’re going to start with the basics, assuming you're just getting into the Vette world. Along with wheel and tire specs, we’ll cover wide and narrow body vehicles, plus discuss different suspension options. Yes, there’s a lot of nuance to this platform if you’re coming from a different scene.

5x120.65 lug pattern
The lug pattern that Chevy uses is 5x4.75 (5x120.65), unfortunately, this rules out a lot of wheels, but on the bright side, we can fix this.
First, the lug pattern is very close to 5x120, but not exact. Can you run 5x120 wheels on your C5 Vette? Technically yes, but like we said in the C6 fitment guide, it comes down to what you can vs should do. You’ll find plenty of cases of people running wobble lug nuts on 5x120 wheels with no issues. It works, but honestly, it feels a bit dirty. One option is converting the PCD.
Converting to 5x114.3 opens up the doors to tons of wheel options including but not limited to JDM wheels. You have two options.
One method involves drilling the factory hubs and pressing in lug studs. Ideally, a machine shop should do this, but it is possible for DIYers too. Also, you’ll need to redrill the rotors to match.
Method 2 involves using parts from a Cadillac CTS, including the hubs and brake rotors (or redrilling the rotors). This is a direct bolt-on option that could be easily reversible in the future. We’re not going to cover all the details of the swap, but you should check out Level Up Garage, who offers a spacer kit for the swap, plus shows how it’s done.
Sure, converting the lug pattern is kind of a drag, but guess what? But how many Hondas, Mitsibishis, Subarus, Nissans, etc, also need similar conversion? Think of this as a 4 > 5 lug conversion on your S13.
There’s also the possibility that your favorite wheels come in 5x120.65, meaning none of this is necessary. CCW, Forgstar, and ESR are a few that cater to Vette owners. Any built-to-order wheels can usually come in any PCD you ask for. Getting the factory lug pattern keeps things super simple, so if it's available, do it!
This guide is going to include both 5x114.3 and 5x120.65 wheel options.
Suspension - lowering your C5
The double wishbone suspension on a C5 is probably a little different than what you’re used to.
A simple way to lower your C5 is with lowering bolts. The factory bolts are adjustable, but aftermarket ones give you a bit more drop. This would be comparable to lowering springs on most platforms, but it’s even cheaper–like 50 bucks. These will give you up to a 1.5 or 2” drop over the stock bolts while retaining the factory driving characteristics.
Some people say the C5 rides like a tractor. If you agree, coilovers might help. They’re often called the best mod you can do for the C5. If you go this route, definitely get the kind that replaces the leaf springs, Silvers and BC Racing are both popular options that do exactly this.
Just because you get coils doesn’t mean you have to go lower. If you’re using your car for any type of motorsport, be it autocross, drift, or anything else, coils are a must-have. They also let you take your car a bit lower, although if you want to go super low, consider the next suspension type.
Bags are for luxury grocery-getting sedans, not sports cars, right? That's what everyone thinks until they try driving a lowered Vette. The combination of transverse leaf springs, a low-hanging air dam, and the overall geometry of these cars makes them scrape on everything.
Air suspension is becoming ever more popular. Some popular brands are Airtekk and Air Lift Performance. These aren’t cheap, but they’ll save you from destroying the undercarriage if you wanna go low.
C5 Corvette wheel and tire fitment
Now that we have gone over the basics, let’s look at what you’re here for: wheel and tire specs.
Narrow body fitment
Again, fitment is the same for all body styles, coupe, FRC, and convertible.

Bottomed out factory bolts |
|
If you want to keep the factory double staggered look, we’d recommend sizing up to 18/19, like this FRC is running. Because the offsets are high, the fitment isn’t too aggressive. This is a pretty basic setup that will let you run wider tires–305/30R19 rears in this case.
This car is on factory suspension with the lowering bolts maxed out. Even with tires this wide, there are no rubbing issues.
TSW is one of those wheel brands that offer 5x120.65 wheels, meaning these will bolt up no questions asked.

5x114.3 swap (other sizes available w/ 5x120.65) Lowering bolts |
|
For symmetry or track duty, a lot of C5s run square setups–the coupe shown here has the same wheel and tire specs all around. These wheels are more aggressive due to the lower offset. The rears fit well but the fronts might give you a tiny bit of poke. If you’re not into this, try something with a higher offset.
A 225/40 tire on a 9.5 wheel will give you a bit of stretch. Something like a 245 or 255/35 will give you a square sidewall if this isn’t your style.
These wheels are 5x114.3. Later on, ESR started offering 5x120.65, although the sizes are more limited. If you want to learn more about ESR, we just did a full episode on them.

Stock suspension on lowering bolts |
|
Here’s a staggered 19” setup on a C5Z. 19x9.5 in the front and 10.5 in the rear with big ol’ tires. There’s plenty of room for wheels with lots of backspacing on these vehicles, which is why we’ll see 11”, or even larger, rears used on stock body cars.
The offset looks high, but this is actually perfect for stock-bodied C5s. This car is on stock suspension with lowering bolts, no excess camber was needed, and there are no rubbing issues.
SSR wheels are not cheap, but the plus side is that you can get them in the original lug pattern, no need to convert.

Air suspension |
|
Some coils might take you this low, but good luck actually driving it. If you want this look you should definitely check out air suspension for the reasons we discussed earlier.
This coupe is running a 3P kit from Air Lift Performance. Recently they started offering coilovers that can be upgraded to air suspension later on. It doesn’t look to be available for the C5 yet, but keep your eyes out for this if you’re on the fence between coils and air.
As far as fitment goes, this is similar to the last, just a bit more narrow. You can still fit decently wide tires on these wheels. In this case, 235/35 in the front and 265/35 in the rear, which should be more than enough for ≈ 400HP NA builds.
These wheels come in lots of bolt patterns, but of course, not the stock Corvette one. This car is running 5x120 with wobble nuts, but note: you could also get these in 5x114.3.
Before getting air suspension: this C5 looked killer with just lowering bolts!

Silvers Coilovers 5x114.3 converted *possibly has camber plates* |
|
Gram Lights, and similar wheels like Work Emotions, look really awesome on these cars, but they’re 5x114.3 only. Is it worth converting? You be the judge.
Once again we see square fitment, but this time with a lower offset. This is pretty aggressive, especially for the front. To make this not poke like crazy, you’ll need some extra negative camber. We don’t know the exact alignment numbers on the C5 pictured, but you may need camber plates to copy this look.
This car is running Silvers coilovers and has zero rubbing at this height (but will scrape on steep driveways).
Widebody C5 wheel fitment
In these fitment guides, we normally don’t get into aftermarket widebody kits for the simple reason that there are numerous kits for any given chassis. Same goes for the C5. We did, however, notice a lot of C5s are running Corvette Creationz fenders, which add 2” to the rear and 1” to the front.
There are enough widebody C5s that we decided to include a few. With widebody fenders, you can go pretty much as wide as you want for wheels and tires. Want a 325 tire on a 12.5” wheel? No problem. To make these look right you’ll want to run a lower offset, which gives the option of more dish and concavity.
*remember there are other kits, so your mileage may vary
If you’re unfamiliar with Corvette body panels, you’ll be pleasantly surprised to learn that these kits are more or less bolt-on. You might have to drill some holes, but compared with most cars the process is straightforward. Simply unbolt the fenders and replace them with your new widebody–no need to cut & shut metal arches like on most cars.

Viking Coilovers Carbon Creationz rear fenders |
|
If you like your C5 extra thick, you could have wide fenders only in the rear–that’s what this FRC is running. We already know about the front fitment, but how about the rear? The final numbers are 18x12.5 +30 with a 315/30R18 tire.
CCW wheels go together with Vettes like peanut butter and jelly. Here’s some insight you may not know about them: they mount the faces through the front rather than the back like on other 3P wheels. This hides about 1” of the lip. Going widebody lets you run lower offsets, which translates to larger lips. Here we see a 3.5” lip in the rear.

C6 z06 suspension 5x114.3 converted Carbon Creationz rear fenders |
|
Here’s what a coupe looks like with the Corvette Creationz rears (only rears). The fitment is very similar to the last, but this one is running 19” wheels.
This car has C6 Z06 suspension and has been 5x114.3 swapped to run these Aodhan wheels.

Carbon Creationz front/rear fenders Factory suspension w/ lowering bolts |
|
If you’re all about symmetry, you’ll want front and rear fenders. This is another Corvette Creationz kit, +1 front and +2 rear.
This one is running a 355/30R19 in the back. Do you need a 355 rear? Probably not, but if you want ‘em, they’re available in our tire section (but this size won’t be cheap). Out front, we see a 19x10 +30. These fenders are only +1, but the big difference is you’re able to run a deep concave with these Forgestars for a bit of extra flare.
Wrap up
‘JDM styling’ doesn’t just mean Japanese wheels. We showed brands like SSR, but also the typical stuff like CCW and Forgestar. Really, a C5 can look good with any style of wheel; it's all about those specs.
To recap, 18 and 19” wheels are by far the most common; you can go squared, staggered, or double-staggered. Offset is higher than most sports cars, but if you want aggressive fitment try something a bit lower, maybe +30. You can go very wide on a C5, especially in the rear.
Once you get that perfect fitment, we want to see your C5 in our Gallery. Bonus points if you're the first to run Work Emotions (we couldn’t find any, but we reckon they’d look sick).
