Advanti Racing Storm S1 15x9 Matte Bronze

RRF, or Rim Rotary Formed, is a flow formed process that results in a product that is stronger/lighter than lesser casting methods. The result is a strong 500 KG load rating in a 15x9 that weighs only 12+ pounds!

* +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).

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!
