Advanti Racing's new Flow Formed line of wheels are STRONGER and LIGHTER than most choices! Flow forming to yield a strong 500kg load rating and a 15x7 that weighs under 11 pounds! No competitor comes even close to these specs at this price!

The flow formed process results in a product that is stronger/lighter than lesser casting methods. Most everything else in this price range is gravity cast, pressure cast, or low pressure cast with heat treatment.

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.

Flow Formed Production Technique results in stronger and more dense final product with less weight than lesser casting methods.

Note we recommend our numerous lug choices with any of our new wheels, stock lugs are too short and fat. 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 15x7 Matte Black

Really happy with these wheels! They came well packaged, are super light, and look great. I got the 949 valve stems (separate order) and switched out the caps for plain black aluminum ones with nothing printed on them. Looks perfect IMHO!

My original 5-spokes were in a bad way, so when I needed new tires, I decided to get new rims as well. I am really glad I went with the Storms. You really can feel the difference in the ride due to the lightness, and the look awesome.

My mechanic did not have any trouble mounting them, as some have stated in other forums based on the spoke going all the way to the rim. Paired with the 949 lugs, this made me love my Miata all over again.

Very satisfied with the look and finish. Paired them with 949Racing Silver Valve stems and Silver lug nuts and it looks on point! So far not a single problem with them (besides not catching the eye too easily) and the fit is perfect with 205/50 tires. Nicely and safely packaged although as the other review states, you do have to get the hub centric rings, valve stems and lugs with these rims.

These wheels look amazing, they are insanely light weight, and are really nicely priced. When you order them they come as is, just the wheels and center caps, you WILL have to buy the centric hub rings, valves stems, and tires.
