Honda Civic Type R FK8 (2017-2021) Wheel Fitment Guide
The FK8 was the first Civic Type R sold in the US: 306 hp, a helical limited-slip differential, adaptive dampers, and Brembo front brakes, offered as a single Touring trim from 2017 through 2021. It rides on a 20×8.5 ET60 wheel with a 245/30R20 tire, a heavy, thin-sidewall setup that's expensive to replace and prone to bending, so most owners downsize to 18″. Because the FK8 is front-wheel drive, every setup in this guide is square (the same size on all four corners). The most common upgrade is an 18×9.5 ET45 on 265/35R18, which bolts on flush at stock ride height.
About this guide: Fitment data is compiled from owner builds across CivicX, r/CivicTypeR, and the wider FK8 community, cross-checked against vendor fitment documentation. Use it as research for your build; ride height, tires, and alignment are still your installer's call.
Every US FK8 left the factory on the same 20″ wheel. The 2021 Limited Edition got a lighter BBS forged version in the same size, and Honda sells a 19″ Modulo forged wheel as an accessory. All three clear the Brembo brakes, and the high ET60 offset on each tucks the wheel deep in the fender to limit torque steer.

A Honda Access / Modulo dealer accessory at roughly $791 per wheel, sold individually. On the FK8 it's an inch smaller and an inch wider than stock, so you'll need 19″ tires; a 245/35R19 keeps overall diameter close to the factory 20″ setup. The gain is weight: about 21 lbs per wheel versus roughly 29 lbs for the standard wheel. Hub hardware and TPMS carry over unchanged.
Aftermarket Options
Aftermarket Wheel & Tire Configurations
Most FK8 builds downsize to 18×9.5 for cheaper, broader tire choice, less weight, and more sidewall to survive real roads. The bolt-on consensus is 18×9.5 ET45 on 265/35R18. From there the offsets step toward more aggressive stances, where the FK8's rear fender flare becomes the limit. Each card below shows what owners actually run and how well it's documented.

⚠️Platform-specific fitment notes — FK8
Ball-seat lug nuts.
The factory lug nuts are ball seat, but most aftermarket 5×120 wheels use a 60° conical seat. A mismatched seat won't clamp the wheel properly, so buy M14×1.5 nuts that match your wheel and don't reuse the factory nuts on conical-seat wheels.
Center bore and hub rings.
The FK8 hub is 64.1mm, and most universal 5×120 wheels are bored to 72.56mm. Every setup below assumes hub-centric rings unless the wheel is bored to 64.1mm; use aluminum rings for track use.
Brembo brake clearance.
The factory Brembo front calipers need at least an 18″ wheel, and spoke shape matters as much as diameter, so confirm clearance for the specific wheel model. The MY2020 refresh moved to two-piece floating front rotors of the same diameter; confirm clearance for your model year. Big brake kits generally need 18″+ for 355mm rotors and 19″+ for 380mm.
Indirect TPMS — no sensors to transfer.
There's nothing to buy or move when you change wheels. After any wheel or tire change, recalibrate under Settings > Vehicle > TPMS Calibration.
FWD scrub radius and the rear fender flare.
Lower offsets add scrub radius and torque steer, which is why owners favor ET38–ET45 on a 9.5″ wheel for the street. The FK8's rear quarter has a metal flare under the plastic lip, so the widest setups (18×10–10.5″) and the lowest offsets can hit it under compression; rolling the fender and adding negative camber are the usual fixes. This is the real difference from the FL5, since the flush fit is the same 18×9.5 ET45 on both.

The consensus FK8 setup, documented on more than two dozen owner builds and listed by vendors as the go-to direct fit. Dropping from the heavy OEM 20″ to an 18×9.5 opens up the full 200-treadwear tire market and adds sidewall for rough roads. It sits flush to nearly flush with no rubbing, including on stock suspension; some owners say it could sit a few millimeters further out. Overall diameter is about 2% smaller than stock, so the speedometer reads slightly high.

The consensus wheel with a narrower, taller tire, and the go-to for mixed-climate daily driving or a winter set, since all-season and winter tires are much easier to find in 255/40R18. It's also the closest 18″ match to the factory overall diameter, within about 1%. Documented on many owner builds, about half on stock suspension, with no rubbing.

For owners who want to keep a bigger wheel while losing weight: an inch smaller and an inch wider than stock, at the same offset as the 18″ consensus setup, with overall diameter within about 1% of the factory tire. Vendors list 19×9.5 ET45, and owner builds run it on 255/35R19, mostly nearly flush. Builds at ET40 on the same tire sit a little further out.
The consensus wheel with the offset dropped to ET38, and the single most-built owner setup on the FK8. It sits flush with a slightly fuller fender than ET45. Most builds report no rubbing, including on stock suspension; a few report slight rub at full turn, usually on lowered cars. A 255/40R18 or 255/35R18 at the same offset is also common.

A full 10″ wheel for more contact patch. Vendors list 18×10 ET40 on 275/35R18 with negative camber recommended and note fender modification may be required, and it's less common on the FK8 than the 9.5″ setups. Owner builds run the same wheel on a narrower 265/35R18. Watch the rear fender flare under compression.

The pokiest common 18×9.5 option, for a show-focused street stance. Vendors list it as a popular fitment with negative camber recommended and note fender modification may be required. Most owner builds report no rubbing, while a few rub, mostly on lowered cars. Narrower 255/35R18 and 255/40R18 tires are also common at this offset and give more clearance.

The widest documented FK8 setup, built for maximum grip on track. The outer lip sits about where an 18×10 ET40's does; the extra width goes inboard, about 13mm closer to the strut. Vendors call for about −2.5° front and −2° rear camber, and it's documented on Swift springs. A 285/30R18 is the wider tire option.

Our Process
What happens when you build with FMB
The setups above are a starting point, not a final spec. Before anything is forged:
FMB sanity check.
We check your configuration against your brake package and the ball-seat lug requirement, and compare it to documented FK8 builds. If it falls outside what we've seen work, we flag it before you commit.
Manufacturer engineering verification.
Our manufacturing partner verifies backspace, caliper clearance for your brakes, and structural spec before production.
Design render approval.
You see the final design and confirmed specs before any aluminum is touched.
Ride height, tires, and alignment are set on the car by your installer, so we can't verify them from our end. That's why the build form asks for your vehicle details.
What wheels and tires come on the FK8 Civic Type R from the factory?
Every US FK8 Touring came on a 20×8.5 ET60 cast wheel with 245/30R20 tires, the same size on all four corners. The 2021 Limited Edition used a lighter BBS forged wheel in the same size with Michelin Pilot Sport Cup 2 tires, and Honda sells a 19×9.5 ET60 Modulo forged wheel as an accessory.
What's the FK8's bolt pattern, center bore, and lug torque?
See the hub & hardware specs above: 5×120 bolt pattern, 64.1mm center bore, M14×1.5 lug nuts torqued to 94 lb-ft (127 Nm). The "80 lb-ft / M12" spec in some listings is for the standard Civic, not the Type R. The factory nuts are ball seat, not the 60° conical seat most aftermarket wheels use, and most universal 5×120 wheels have a 72.56mm bore that needs hub-centric rings.
What's the deal with ball-seat lug nuts on the Type R?
The FK8's lug nuts have a rounded (ball) seat, while most aftermarket wheels are machined for a 60° conical seat. If the two don't match, the wheel won't clamp fully against the hub, which is a real safety issue. Buy M14×1.5 lug nuts that match your wheel's seat, and keep the factory nuts with the factory wheels.
What's the minimum wheel diameter that clears the Brembo brakes?
18″. The factory Brembo four-piston front calipers won't clear a 17″ wheel, so FK8 owners stop at 18″ when they downsize. Spoke shape matters too, so confirm clearance for the specific wheel model. With a big brake kit, plan on 18″+ for 355mm rotors and 19″+ for 380mm.
Why do most FK8 owners downsize from 20″ to 18″?
The OEM 245/30R20 is expensive, has a thin sidewall, and the heavy 20″ wheel is prone to bending. An 18×9.5 opens up the full performance tire market, cuts cost and weight, and adds sidewall. A 265/35R18 is about 2% smaller than stock, and a 255/40R18 is within 1%. Aftermarket 20″ setups are rare; owners who want a bigger wheel usually go to 19″.
What aftermarket sizes fit at stock ride height?
18×9.5 ET45 on 265/35R18 is the bolt-on consensus, confirmed on dozens of owner builds; 255/40R18 on the same wheel also fits cleanly. 18×9.5 ET38 on 265/35R18 is the most-built owner setup and works at stock height too, with occasional light rub at full lock. 19×9.5 ET45 on 255/35R19 is the 19″ option. ET35 and the 10–10.5″ widths usually need camber and fender work.
What's the difference between a flush and aggressive setup on the FK8?
Flush means the tire sits even with the fender; on the FK8 that's 18×9.5 ET45, the same flush spec as the FL5, with ET38 sitting just a little fuller. Aggressive puts the wheel face past the fender line, using ET35 and lower or 10–10.5″ widths. On a front-drive car, aggressive setups add torque steer and usually need camber and attention to the rear fender flare.
Will Modulo or FL5 wheels fit my FK8?
Yes. The FK8, FL5, FK2, and Integra Type S (DE5) share the same 5×120 pattern, 64.1mm bore, and ball-seat lugs, so their wheels bolt on. The Modulo and FL5 factory wheels are 19″, so you'll need 19″ tires. For the widest setups, the FK8's rear fender flare leaves less room than the FL5's body, so don't assume an aggressive FL5 fitment carries over.
Can I use BMW or other universal 5×120 wheels on my Type R?
The bolt pattern matches, but you'll need hub-centric rings (72.56 to 64.1mm, aluminum for track use) and conical-seat M14×1.5 lug nuts. Check the offset too: many BMW wheels are built for rear-drive geometry and sit too far in or out on the Type R.
Is a staggered setup a good idea on the FK8?
No. The FK8 is front-wheel drive, so wider rear tires add nothing. Some time-attack cars run a reverse stagger for front grip; one documented FK8 runs 18×10.5 ET35 on 295/30R18 up front and 18×9.5 ET45 on 265/35R18 in the rear. The community advises against it for street cars.
What winter wheel and tire setup works on the FK8?
An 18×9.5 ET45 wheel on a 255/40R18 winter tire, the same as the daily setup above. It's within about 1% of stock diameter, and winter tires like the Bridgestone Blizzak WS90 are far easier and cheaper to find in 18″ than in the OEM 20″ size. A cast or flow-formed wheel is fine for a winter set.
Do I need wheel spacers on the FK8, and what size?
Only to adjust a wheel you already have; with new wheels, just order the right offset. A 15–20mm hub-centric spacer moves the factory ET60 wheel toward flush. Check thread engagement, because thin spacers on the factory pressed-in studs may not leave enough thread to torque safely, and re-torque to 94 lb-ft after a short drive.
