Kōgeki means "attack" in Japanese - seemed appropriate since these are intended for attacking your favorite corners, whether they're on a track or your favorite backroad.

These flow formed wheels are exclusive to Flyin' Miata and built for us by a major wheel manufacturer. They're high-pressure cast for less porosity, then the rim is spun-forged. They were designed specifically for the ND Miata for the perfect fit under the fenders. They clear all stock calipers as well as every upgrade brake option we sell. If you want to check against other brake setups, you can use our template.
17x9 ND Kōgeki fitment template

Because we know they'll be used hard, they're rated for 550 kg (1213 lbs) of load instead of the more common 500 kg to give some extra margin (using J2530 JWL standards). They also have knurling to prevent tire slip under extreme conditions.

And seriously, just look at them. Yummy.

You can fit a 225/45-17 or 235/40-17 under most unmodified fenders. With a 17x9, you can run a 245/40-17 with some fender rolling depending on alignment. If you add spacers, you are more likely to need fender modifications. We recommend ARP studs with any spacer thicker than 3mm. The wheels are compatible with stock lug nuts but light wheels deserve light lug nuts!

Be aware that at full lock with 235+ tires, you might see slight contact between the tire and front control arms on the unloaded side. This is more of a polish than a hard contact (no structural damage will happen to the tire or control arms), but be aware that it's a possibility. Most - but definitely not all - 235s should be fine, 225s will be fine, and 245s are virtually guaranteed to have this slight contact. All will function fine, it's just a matter of whether that polishing of the control arm is an issue or not. 

These are fully compatible with factory TPMS sensors, as well as the sensors we sell. And likely most others, although we can't guarantee that for sensors we haven't tried ourselves.

You can use stock lug nuts and chrome sockets, but it's close - 21mm impact sockets probably won't clear, 19mm impact sockets (as used with our 19mm lug nuts) probably will, but be careful. Chrome 19mm sockets should have plenty of room. 

Note that wheels are sold individually, make sure you order 4! Can be used on an NA or NB but you will need a 10 mm spacer and 2.5" diameter springs for optimum fit.

Also available in 17x8. 


17x9: 16.8 lbs, +45 offset, 67.1 mm hub bore

We recommend that any wheel used on the track be inspected regularly for cracks and fatigue as part of proper maintenance. 

Note that the gloss black color has been discontinued and won't be replenished, although we do still have a couple left as replacements.

Even Fits Weird Looking Miatas

Used some 10mm spacers, but they fit great on my ""miata"" despite it looking a little funky. Happy with the price and finish, one of the few wheels available in the sizes I needed.

Perfect all around wheel for any Miata!

I have these wheels on my ND in the bronze finish, they see 3 seasons of driving + autocross and light track use. The wheels look great on my ND and the finish is high quality (I have them ceramic coated so hopefully it will last a long time!) Plus, they're SUPER LIGHT. What's not to love, especially for the price they're offered at?
The car is on Meisterr Clubrace coilovers and they see the horrible roads here in CT, and no issues at all in the past 12k miles or so. Thanks those at Flyin who released these, they're a perfect wheel for the Miata! I'll be getting another set solely for track use soon!

Perfect rim for the ND!

I've had these on for the last 6 months or so, and I love them. They look great and are drastically lighter than stock. I'm running the 225/45R17 Yoko run flats on my 2019 ND RF with Fox suspension and willwood brakes. Fit great in every way. I highly recommend these rims.
