Why upgrade to BMW wheel studs M14 instead of keeping the factory bolts?

Factory BMW wheels use bolts that thread directly into the hub carrier — the wheel must be held in position while each bolt is started, which makes wheel changes more difficult, particularly at track days or roadside. BMW wheel studs M14 protrude from the hub and act as a guide for the wheel, allowing it to hang on the studs while each nut is started. This makes wheel changes faster, easier, and reduces the risk of cross-threading.

What length should I choose — 70mm or 80mm?

70mm studs are the standard choice for most road and track use, providing adequate thread engagement with both stock and aftermarket wheels. 80mm studs are suitable where spacers are fitted or where additional thread engagement is needed for wider aftermarket wheels. Check your wheel thickness and any spacer dimensions before ordering.

Are these BMW wheel studs M14 compatible with both F-chassis and G-chassis models?

Yes. The M14x1.25 thread specification is shared across F-chassis and G-chassis BMW 1, 2, 3, and 4 Series as well as the M2, M3, and M4 across both generations. The same stud also fits the F56 MINI Cooper, Cooper S, and JCW.

What is the 6mm Allen drive on the stud for?

The 6mm internal Allen drive in the end of each stud allows the stud to be threaded into the hub using an Allen key for precise installation torque. It also enables removal of individual studs if needed without damaging the surrounding hub carrier.

Are the aluminum nuts safe for track use?

Yes. The 7000-series aluminum nuts are rated for vehicles up to 2500kg. 7000-series aluminum has higher tensile strength than the 6000-series alloy used in many budget wheel nuts. The 19mm conical seat maximizes contact area at the wheel for secure fitment. These are not a locking or anti-theft solution.

Description

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

BMW wheel studs M14 from MMX Performance are a complete stud and nut upgrade for F-chassis and G-chassis BMW models and the F56 MINI Cooper converting from the factory bolt fitment to a stud-and-nut system for easier wheel changes and more consistent torque on track days and regular servicing. Available in 70mm or 80mm lengths, each stud is heat-treated high-carbon steel with a chrome-plated finish for corrosion resistance; a full M14x1.25 thread runs the wheel side, with 8mm of unthreaded shank at the hub face providing brake disc clearance on each stud. The included 7000-series aluminum open-ended nuts are gloss anodized and feature a knurled outer collar for easy finger threading, plus a 6mm internal Allen drive for precise torque with a wrench. Oversized 19mm conical-seat nuts provide maximum contact area at the wheel for secure fitment. Rated for vehicles up to 2500kg. Compatible with F-chassis and G-chassis 1 Series, 2 Series, 3 Series, 4 Series, M2, M3, and M4 across both generations, plus the F56 MINI Cooper, Cooper S, and JCW.

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.
