ECS BMW Wheel Bolts, Wheel Studs and Nuts for BMW X Series E71 (2008-2014)

Clear BMW chassis

Please ensure your correct model is selected

Any time you use a wheel spacer you MUST have a longer wheel bolt or wheel stud to properly fasten the wheel to the hub. We offer extended wheel spacer bolts in silver and black finish in a variety of lengths to fit many spacer sizes. We're up to date on the different thread sizing as well - 12x1.5, 14x1.25, and 14x1.5 so we can supply wheel bolts for just about any BMW or MINI.

Add the spacer thickness to your stock bolt length and that is your ideal extended bolt length. We generally sell bolts by spacer thickness but there may be exceptions. It's always best to measure from the wheel bolt you're currently using. When we list the total length of a bolt it's from the base of the mounting seat to the tip. To be considered safe, a 12x1.5 wheel bolt needs 10mm (6.5 turns) of thread engaged; a 14x1.25 or 14x1.5 bolt needs 12mm (9.0 and 7.5 turns) of engaged thread.

Enhance wheel replacement efficiency on your BMW with a stud conversion kit, facilitating quicker and easier wheel changes. This comprehensive kit includes:

  • Conical Seat Lug Nuts (20)
  • 75mm Wheel Studs (20)

The installation of these studs provides a permanent wheel-hanging solution, saving time and reducing hassle during wheel changes. By simply screwing in the supplied studs, you'll be ready to go.

Benefits of using wheel studs instead of wheel bolts:

  • Some racing regulations mandate wheel studs for enhanced wheel-to-hub contact, ensuring added safety.
  • Wheel studs accommodate various spacer widths, eliminating the need for custom bolt lengths when using spacers.
  • Simplifies wheel installation; the studs act as wheel hangers while nuts secure the wheel in place.
  • Reduces wear on wheel hubs as wheel studs remain in the hub, unlike constantly removed and installed wheel bolts.
  • Facilitates quick and easy tire changes as wheel studs stay in place.

Note: Use thread-locking compound during installation and torque studs to 15Nm for optimal performance.

Upgrade your BMW's wheel system with this stud conversion kit for improved convenience and functionality.

If you are a performance-minded enthusiast looking to save weight wherever possible or just want a set of very high quality wheel bolts that won't rust, ECS Titanium Wheel Bolts are exactly what you need. ECS Titanium Wheel Bolts are 50% lighter than steel bolts of the same size, thus reducing rotational mass on the vehicle. They are CNC'd from annealed titanium alloy and when tested to class 10.9 fastener proof load requirements, they showed no signs of fatigue or failure. Bolt Specifications: Diameter: 14mm Thread Pitch: 1.25mm Length: 27mm, 35mm, 40mm, 45mm Head: 17mm Seat: Conical Seat Before installing ECS Titanium Wheel Bolts on your vehicle, please ensure the threads on the hub are thoroughly cleaned to remove traces of zinc from previously installed wheel bolts. Any zinc left behind can lead to fatigue and cracking of the titanium alloy. *When installing wheel spacers, add the size of the spacer to the length of the OE wheel bolt for proper fitment (ex. 27mm Length OE Wheel Bolt + 15mm Wheel Spacer = Requires a 42mm Length Bolt)
