What BMW models do the MMX BMW E-chassis wheel spacers fit?

The MMX BMW E-chassis wheel spacers fit the full range of BMW E-series models, including the 1 Series (E81, E82, E87, E88), 3 Series (E21 through E93), 5 Series (E12 through E61), 6 Series (E24, E63, E64), 7 Series (E23 through E68), 8 Series (E31), X1 (E84), X3 (E83), X5 (E53), X6 (E71), Z3, and Z4. They do not fit M3, M5, M6, X5 M, X6 M, Z3 M, or Z4 M variants.

Why are hubcentric spacers better than non-hubcentric spacers?

Hubcentric spacers use a precisely machined alloy spigot that locates the wheel directly onto the hub center, ensuring the vehicle's weight is supported by the hub rather than the wheel bolts. This eliminates vibration at speed and provides a safer, more stable driving experience. Non-hubcentric spacers are not recommended for performance vehicles.

What sizes are available and how much track width do they add?

The MMX E-chassis wheel spacers are available in 12mm, 15mm, and 18mm widths. Running one spacer per side adds 24mm, 30mm, or 36mm of total track width per axle respectively.

Do bolts come included?

Yes. Each kit includes ten extended-length grade 10.9 carbon steel black wheel bolts, so no separate hardware purchase is required for a standard installation.

How are the MMX wheel spacers sold?

The MMX BMW E-chassis wheel spacers are sold as a pair, covering one axle. Two pairs are required to space all four wheels.

Can these be returned after purchase?

No. MMX wheel spacers are non-returnable once purchased. If you have fitment questions before ordering, contact us and we will confirm compatibility for your specific model.

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.
