Kogeki 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 NC 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 690 kg (1521 lbs) of load (using J2530 JWL standards). They also have knurling to prevent tire slip.
And seriously, just look at them. Yummy.
You can fit a 225/45-17 or 235/40-17 under unmodified fenders on the 17x8. With a 17x9, you can run a 245/40-17 with some fender rolling depending on alignment.
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.
Be sure to order 4 wheels if you want 4.
17x8: 15.6 lbs, +48 offset, 73.1 mm hub bore
17x9: 17.5 lbs, +48 offset, 73.1 mm hub bore
We recommend that any wheel used on the track be inspected regularly for cracks and fatigue as part of proper maintenance.
