Tire Size breakdown:
-195/50 and 205/50: not recommended
-225/45: Tires fit NB fenders with no mods needed given 1.5 negative camber or better, fits NA with slightly rolled fenders and that negative camber
- 225/50: require rolling and pulling fenders, removing liners on NA, NB only requires slight roll.
-235/50 Toyo R888: requires rolling and pulling on NA, roll only on NB, will rub top of tire at full compression.
-275/35 require rolling and pulling, removing liners on NA, flat roll on NB. 20-30mm spacer recommended to fill aftermarket flares.

Will NOT clear stock suspension, need coilovers with 2.5 inch diameter springs or narrower and expect may still rub at full lock (which is not a real issue since full lock is only possible at parking lot speeds).

ABOUT ADVANTI RACING: Advanti Racing wheels was established in the mid 1990s. Their racing experience includes supplier and sponsor of the Formula One Scuderia Toro Rosso team, among others, and that experience is reflected in the quality wheels they produce. Each wheel is designed and engineered in-house by YHI Manufacturing to the highest quality and testing standards, including JWL, JWL-T, VIA and TUV.

Brian's Application Notes: WOW, what a bargain, never dreamed we would get flow formed strength in this price range. The benefit is wheels that are BOTH stronger AND lighter! You can buy lots of regular cast wheels for this same price and more that are not near as strong.

12mm bolt holes are perfect for centering wheel on Miata, but some MINI customers would need to change to 12mm studs. Stock lugs too short and fat, see our lug upgrades.

Note we recommend our numerous upgraded lug choices with any of our new wheels. Unlike the short and fat stock lugs that will result in scratching new wheels, all our replacement lugs have the socket tool bottom on the lug rather than the wheel surface, and are longer for more engagement with stud surface so they also stay tighter.

Customer Reviews

Advanti Racing Storm S1 15x9 Grey +35

I bought these to run in the SuperMiata race series and wrapped them in the spec tire 225/50/15. They look awesome and it's great to have such a light wheel that's strong enough to hold up to the pressures of wheel to wheel racing.

There is a bit of a lip that likes to catch small pebbles in it. Just takes a flathead screwdriver and a few minutes to scrape them out. You can fix that by never leaving the racing surface :)

Also, lighting fast shipping and great communication from the crew at Good-Win. Thanks!

These wheels in 15x9 size with Toyo Proxes RA1s feel amazing at AutoX. No matter how hard I pushed them, I couldn't get them to break loose. On a dry practice skid pad, I even tried a few clutch-drops and at most these tires would give out a squeal, but not break loose. At the last autoX I did at Sonoma Raceway, my 2002 Miata was getting the same lap times as a Cayman S. Granted, I have the Xida coilover setup from 949Racing.

The wheels look great on the car and carry breakdust like a champ. And the price is unbeatable! I would highly recommend these to anyone.

I've been looking for wheels for over a year and couldn't find anything light weight that also looked good. I actually wasn't completely in love with the storms until I put them on the car. I bought them believing that they looked descent but never thought that they would look so perfect! Especially with grey on green. I actually have always gone with black wheels on my previous cars but I knew it would be to dark for a dark green car so I took a leap of faith on the greys and I'm so glad I did.

I actually think that I have the best looking wheels you could find for a NB. I'm so happy with them. On top of that they are probably the lightest wheels and were at a price lower than anything else. You guys literally topped the three categories I was concerned with in a wheel. Looks, weight, price. Seriously, if they weren't on my car now I would have to pinch myself because this deal seemed to good to be true. Thank you to everyone at Good-Win Racing!!!
