Kogeki 17x9 flow formed wheel for ND

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 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.

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!

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. 

Specifications:

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.
