Do the BMW locking wheel nuts M14 work with the MMX wheel stud conversion kit?

Yes. The BMW locking wheel nuts M14 are designed specifically as a companion to the MMX M14x1.25 wheel stud conversion kits, compatible with both the 70mm and 80mm stud lengths. They replace one standard MMX nut per wheel so all four wheels are covered by a single set.

How do the BMW locking wheel nuts M14 prevent theft?

Each locking nut uses a unique security pattern on the drive socket that matches only the included removal tool. Without that specific tool, the nut cannot be driven off using standard sockets or removal tools, preventing opportunistic wheel theft.

Will the BMW locking wheel nuts M14 match the appearance of the standard MMX nuts?

Yes. The locking nuts use the same gloss black anodized finish as the standard MMX wheel nuts, integrating seamlessly into the existing stud conversion with no visual mismatch between the locking and non-locking positions.

Are wheel studs included with the BMW locking wheel nuts M14?

No. The BMW locking wheel nuts M14 set contains four locking nuts and one removal tool only. Wheel studs and standard non-locking nuts are sold separately as part of the MMX wheel stud and nut conversion kits.

What happens if I lose the removal tool?

The removal tool is matched to the unique security pattern of your specific set of BMW locking wheel nuts M14. Keep the tool in a safe, accessible location — without it the locking nuts cannot be removed with standard tools. Contact MMX or Bulletproof Automotive if a replacement tool is needed.

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.
