MMX Wheel Stud & Nut Set (M14x1.25) for BMW F-Chassis and G-Chassis | F56 MINI Cooper

The MMX Wheel Stud & Nut Set (M14x1.25) is a premium hardware upgrade engineered for BMW F-Chassis and G-Chassis models as well as F56 MINI vehicles. Each set includes heat-treated high-carbon steel studs in your choice of 70mm or 80mm lengths, finished in durable chrome plating for longevity and corrosion resistance. The included 7000-series aluminum nuts are lightweight and open-ended, featuring a gloss anodized finish for durability and visual appeal. With a knurled outer collar for enhanced grip and a 6mm internal Allen drive for precise installation, this kit is designed for ease of use and secure fitment. The studs feature 8mm of unthreaded shank for optimal brake disc clearance and oversized 19mm conical-seat nuts for maximum contact and safety. Rated for vehicles up to 2500kg, this set is a high-performance solution — though not intended as a locking or anti-theft system.

Approved max vehicle weight is 2500kg / 5512lbs
This is not a locking or security solution
As with all anodized finishes, do not clean these nuts with aggressive acidic or alkaline cleaners otherwise the finish will be damaged
Use only pH balanced cleaners (i.e. non-acid, non-alkaline, non-solvents). Never use any type of wheel cleaner or any chemicals including abrasive compounds on the nuts. Water and mild soap is recommended for wash. Using commercial carwashes who use aggressive chemicals such as TFR is not advised either.

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.
