Advanti Racing's flow formed line of wheels are STRONG and yet LIGHTER than most choices

This is MATTE BRONZE finish is exclusive to Good-Win Racing. Factory charges more for this custom color run, we think the results are worth it!

The flow formed process results in a strong product that includes a 500kg load rating for a 15x8 that weighs just 11+ pounds! Most wheels sold elsewhere in this price range are gravity cast, pressure cast, or low pressure cast with heat treatment.

These are a special order in Bronze and we are the ONLY vendor in the world to stock this color. It costs more for us to get them, we think it is worth it for those seeking something a bit more special.

1990-2005 Miata Brake Clearance Notes:
- Clears all factory brakes
- Clears Wilwood 11" BBK
- Clears Stoptech 11" BBK
- Clears our old 11" Version 4 BBK
- Clears our 11.75" Version 5 BBK
- If you have another big brake kit, please contact us to confirm clearance.

Tire Size breakdown:
-205/50 fits NB Miata fenders with 1.2 negative camber or better, NA Miata needs that camber and slightly rolled fenders.
225/45/15 needs fender roll for all years at this offset. 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!

The black and grey colors often weigh in as little as 11 pounds even, this Hyper Silver color is a thicker and more expensive finish consisting of powder coating and clear coat over, typically weighs a few ounces more than the other colors but still ultra light and you get an even more durable and deep gorgeous finish.

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.

Note we STRONGLY recommend our numerous upgraded lug choices with any of our new wheels, stock lugs too short and fat and will scratch these 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 15x8 Matte Bronze

Really happy with these wheels. I paired them with continental extreme contact sport tires in 205/50r15. They went on a bone stock nb2 and fit perfectly, no rubbing or other clearance issues. There's just a little bit of poke which gives a nice sporty look. They're super light weight, look great, and aren't ridiculously expensive. These are a great option for anyone looking for new wheels for an nb!

I have 6 sets of Avanti Storm wheels that I run on my 2 Honda Civics. With the same 4x100 and similar offset to the Miata, they are a great match for a Civic. They are light and strong. Never had any issues with them. I've even had a few pretty hard wheel to wheel contact with other cars in races and they showed almost no signs of damage at all. Very happy with these.

After searching for about a year and comparing these wheels to several other options I decided to go ahead and order them. I originally saw these on a white NB and fell in love with them and I couldn't be happier with the way the bronze looks on my montego blue NA as well. The fenders do need to be rolled and different lug nuts used but those were both things that the previous owner had already done to the car so I was fortunate enough to not have to worry about them. I wrapped them in 205/50/R15 Kumho Ecsta PS31 tires which give the wheel a perfect look and fill out the fenders nicely in my opinion. There is a huge difference in how the car both looks and handles now and I get excited every time I'm walking towards it knowing that I'm that much closer to getting the car to how I want it. My only regret is not purchasing these sooner!

Took me a long time to decide what wheels to get for my project Miata. Really glad that I went with these for a few reasons.

1. The price (I did buy them on sale; $204 down to $169)
2. The color (really fresh; looks like it will mesh well with most of the colors I had in mind for when I change the color of the car)
3. The fitment is damn near perfect (you will need to roll your fenders on an NA, but only a little)

The only down side of these wheel is that you will need to also buy new lugs in order to not scratch the wheels during installation. I picked up a set at my local auto shop and they worked with no problems.

If I had to do it over, I would 100% buy these wheels again. Completely changed the look and stance of my project car. Got me excited to start working on it again.

I must admit, buying aftermarket rims for your car for the first time can be daunting. There's really no guarantee on fitment and it can be a pain finding "the ones" for your car. All I knew was I wanted bronze and as I was about to pull the trigger on some different wheels that wouldn't fit my car, Goodwin sent me the email about these new wheels in an exclusive color; I instantly bought them. After having them wrapped in Nitto Neo-Gens (205/50/R15), I just fell in love with the way they looked and felt. My total came out to $1200 with a little bit of modification on the fenders and suspension.

Really couldn't be happier.

The Good:
- Color and finish are amazing
- Lightweight and durable (flowform is a huge plus)
- Perfect offset and width for a street or track build

The Not So Good:
- Needs fender modification for flush fitment
- Seriously good suspension mods will be required if you want to run these on the street with lowered suspension
- You need to buy different lugs for these to work, stock don't fit and I ended up spending $80 just on lugs
