ECS BMW Wheel Bolts, Wheel Studs and Nuts

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 your wheel changing experience with a stud conversion kit tailored for your BMW, designed to streamline and expedite the process. The kit comprises:

  • Conical Seat Lug Nuts (10)
  • 55mm Wheel Studs (10)

This conversion provides permanent wheel hangers, minimizing time and hassle. Simply screw in the provided studs for quick and easy installation.

Why Choose Wheel Studs Over Wheel Bolts?

  • Added Confidence: Some racing regulations require wheel studs for improved wheel-to-hub contact, ensuring additional security.
  • Versatility for Spacers: Wheel studs accommodate various spacer widths in one application, eliminating the need for custom bolt lengths with different spacer sizes.
  • Ease of Installation: Wheel studs simplify the wheel installation process while the nuts secure the wheels in place.
  • Reduced Wear: Wheel studs in the hub reduce wear on wheel hubs, compared to frequently removing and installing wheel bolts, enhancing longevity.
  • Quick Tire Changes: Wheel studs facilitate swift and effortless tire changes or removal.

*Note: Apply thread-locking compound during installation and torque studs to 15Nm. These studs support spacers up to 10mm in size.*

ECS Tuning sets the standard for conical seat wheel bolts, meeting rigorous safety and testing standards while adding a touch of style with a durable black zinc coating. These bolts are designed to provide longevity and secure your wheels correctly, ensuring peace of mind when you hit the road. Key Specifications: Diameter: 14mm Thread Pitch: 1.5mm Length: 28mm Please note: When installing wheel spacers, consider adding the spacer size to the length of the OE wheel bolt for a proper fitment. For example, a 27mm Length OE Wheel Bolt with a 15mm Wheel Spacer requires a 42mm Length Bolt for a secure fit. ECS Tuning's Black Conical Seat Wheel Bolts are the ideal choice for BMW owners who prioritize both safety and style. Upgrade your wheel fasteners and ensure your wheels are not only fastened correctly but also exude a touch of sophistication on the road.
