What size BMW G90 M5 wheel spacers should I choose?

The 15mm option is the most popular for the G90 M5, giving a flush fitment with the aggressive factory fender line. The 12mm is a more conservative flush look for owners who want a subtle improvement, and the 10mm suits applications where brake or suspension clearance is the primary goal rather than stance. Measure your current wheel-to-arch gap before ordering.

Why are hubcentric BMW G90 M5 wheel spacers important?

Hubcentric spacers use a precision-machined spigot to locate the wheel concentrically on the hub, ensuring the wheel is centered by the hub rather than by the bolts alone. This eliminates the vibration risk that non-hubcentric spacers introduce, which is critical on a high-performance vehicle like the G90 M5.

Do these spacers fit the G99 M5 Touring as well as the G90 M5 Sedan?

Yes. The MMX wheel spacers fit both the G90 M5 Sedan (2024-present) and the G99 M5 Touring (2024-present).

How many pairs do I need for the full car?

Spacers are sold as a pair, covering one axle. To fit all four corners of the G90 M5, two pairs are required — one for the front axle and one for the rear.

Description

MMX Hubcentric Wheel Spacers for G90 / G99 BMW M5

BMW G90 M5 wheel spacers from MMX Performance are precision-machined from aerospace-grade 7075-T6 aluminum and fully hubcentric, delivering a flush, aggressive stance while improving lateral stability and brake clearance on the G90 M5 Sedan and G99 M5 Touring. The hubcentric spigot ensures exact wheel centering and vibration-free operation at all speeds, unlike non-hubcentric alternatives. Available in 10mm, 12mm, and 15mm widths, each pair is supplied with ten extended-length grade 10.9 carbon steel black wheel bolts to maintain correct thread engagement after the spacer is fitted.

Why hubcentric matters

MMX hubcentric spacers feature a precision-machined alloy spigot that locates the wheel concentrically on the hub, eliminating the vibration and imbalance risk associated with non-hubcentric designs. For performance applications like the BMW G90 M5, hubcentric fitment is the only safe choice.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
