Advanti Racing's flow formed process results in a product that is stronger and lighter than lesser casting methods. The result is a Strong 500 KG load rating in a 15x9 that weighs only 12+ pounds!

* 15x9 4x100
* +35 offset
* 12.2-12.5 lbs
* Flow Formed construction
* 73mm center bore (takes our 73/54 hub rings for Miata sold on this site).
* Clear coated finish
* Cap included
* Valves not included
* Fits 225/45, 225/50, 245/40, 245/50, 275/35 tires.
* JWL and TUV approved
* VIA 500kg certification

Always check clearance during install and after car is lowered to the ground, failure to do so can result in damage, death, tires cut on fender lips, and other bad stuff! Takes optional 73/54mm hubcentric rings also available on this website.

Tire Size breakdown:
-195/50 and 205/50: not recommended
-225/45: Tires fit NB fenders with no mods needed given 1.5 or better negative camber, 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.

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 many lug upgrades.

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), 3mm spacers can be added if you are running so much camber that you rub inside control arms, etc.

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, samples weigh as little as 12.2 pounds, we 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. Note that all other things equal, higher spoke count is stronger than lower spoke count, part of the reason this wheel is 10 spokes!

Result is stronger and more dense final product with less weight than lesser casting methods!

Note we STRONGLY recommend our numerous upgraded lug choices with any of our new wheels, stock lugs are too short and fat to fit properly. 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.

Thanks to friend Phil Sokol for the good pictures shown here (not the pic on the scale!).

Advanti Racing Storm S1 15x9 Matte Black

Super sweet looking wheels, still waiting to install them because I got the car in the paint booth this weekend if not first thing next week.

The wheels came in well packaged around a week after my order. They were exactly how you would expect new wheels to look. Not a mark.

I wrapped these in a set of 225/45r15 BFG Rival 1.5s. I weighed each stock 17in Racinghart wheel with stock tires and did the same for the S1s with the Rivals. The S1s were an average of 3.9 lbs less per wheel/tire and a total of 15.6lbs lighter.

The 225s end up being stretched a slight amount but at 12in rear height and 11.75in front height on vmaxx classics I have experienced zero rub. However, I do not track the car nor do I have a ton of miles on them yet.

I went with a set of Muteki lugs which fit perfectly on the wheel.

Overall they look great, the wright savings is good. You can feel it in the steering wheel right away. Happy with the quality so far and would make the same purchase again.

Wheels fit perfect (15 x 9)and look badass (for a Miata), running 225-45-15 hankook tires. Ride height is 11.25 front 11.5 rear with skunk2 coilovers. had to roll the fender lips all around, no rubbing now.
FYI - i didnt use a fender roller, for $34 i bought a harbor freight body and fender kit, i used the large radius dolly to massage the fender lip.

Bought these wheels for a 1993 Mazda Miata. Wrapped them in a 225/45 Toyo Proxes R1R. The totally transformed the look of my car. Light weight and the can take a beating. A+

15x9 storms in black - extremely light weight, beautifully deep and very strong. Can't say I can find any negatives on these wheels. They are balanced great and look awesome wrapped in 225/45/15 bfg rivals.

I bought a set of black Advanti Storm S1's in a 15x9 for my Mazdaspeed Miata. These wheels are phenomenal. Very lightweight, beautiful finish, and all around a very well built product. When experimenting with fitment (without tires) it looks as though the rears clear my stock suspension in the rear and the front clears with a 5mm slip on spacer. Delivery was quick and well packaged. I'm very happy with my purchase and I'll definitely be a returning customer. Thanks, Good Win Racing!
