Kōgeki 17x8 flow formed wheel for ND Miata

Show us your Kōgeki wheels – Use #kogekiwheels to share your car with the world!

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. Flow forming takes a cast center and spin forges the barrel for strength where it's needed, making a strong wheel at an affordable price. They were designed specifically for the ND Miata for the perfect fit under the fenders. They clear non-Brembo stock calipers as well as every upgrade brake option we sell. You can use our template to check clearance against other brake setups.

If you have the Brembo brakes (OE or the Brembo big brake kit specifically for the Cup race cars), you'll need a 5mm spacer to clear the caliper with this wheel. Even with that spacer, 225/45-17 tires should clear the stock fender fine. A 235/40-17 might be okay, but is at a higher risk of interference, depending on the specifics of your setup. Without the 5mm spacer (if you have not-Brembo brakes), you should still be fine with the 235. Remember that we recommend stronger and longer wheel studs with a spacer thicker than 3mm. 

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. Want more pictures? Take a look at what our customers have shared:

You can fit a 225/45-17 or 235/40-17 under unmodified fenders on the 17x8. If you add spacers, you are more likely to need fender modifications (check notes in Brembo paragraph). We recommend stronger wheel studs with any spacer thicker than 3mm. The wheels are compatible with stock lug nuts but light wheels deserve light lug nuts!

Note that if you have especially wide 235/40-17 tires (such as the Toyo R1R, which is almost 1/2" wider than other 235s), you might experience slight rubbing on the front lower control arm at full lock. 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. 

These are fully compatible with factory TPMS sensors.

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 likely need a 10-20 mm spacer for optimum fit depending on tire size.

Also available in 17x9. 

Specifications:

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