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 NA/NB Miata to ensure clearance for all FM and stock brake setups and for the perfect fit under the fenders. Because we know they'll be used hard, they're rated for 550kg (1213 lbs) of load instead of the more standard 500 kg (using J2530 JWL standards). They also have knurling to prevent tire slip.
The spoke design allows for a massive amount of brake clearance, more so than any other 15x9 we've tested.
And seriously, just look at them. Yummy.
You can fit a 225/45-15 on a 9" wheel under unmodified NB fenders, although NA fenders will require a roll. 245/40-15 might need a slight roll on an NB and will need a more aggressive roll on an NA. The 9" wheels won't fit with stock diameter springs (such as the FM springs), but they will fit with a 2.5" or smaller spring (such as the Fox or V-Maxx). The wheel also has stupendous amounts of brake clearance, which you can check with our printable template.

Centering rings aren't required, as the wheel will center on the taper of the lug nuts, but centering rings do make installation a tick easier.
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.
If you choose to upgrade your wheel studs (recommended if spacers are used or if the car will see extreme use), the 1990-93 NA6 uses 0.507" studs on all four corners. Other NAs and NBs use 0.579" on the rear and 0.507" on the front.
Note that wheels are sold individually, so make sure you order 4.
Also sold as a 15x8.
Specifications:
15x9: 13.45 lbs, +36 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.
