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.

Unsure of what size spacer will work best for you? This professional kit includes 1mm, 2.5mm, 5mm, 10mm, and 15mm spacers with wheel studs and nuts for you play with. These are not the same spacers that we sell and they cannot be used to drive on. But with the studs installed the car can be lowered to the ground and rolled to check for clearances. These test fit spacers are drilled to fit the standard BMW 5x120 bolt pattern as well as 4-lug 4x100 (and VW/Audi bolt patterns too). You can stack spacers to achieve the perfect clearance. When you're ready call us to order the spacers you need (Turner spacers come in 3mm, 5mm, 7.5mm, 10mm, 12.5mm, 15mm, 17.5mm, 20mm, 25mm, and 30mm spacer thicknesses).

These spacers are not for driving on. They lack the hubcentric lip that BMW wheels are designed to work with. Driving on studs alone will lead to a failure.

Two ways to buy -

• Own. Just as it says, you buy this kit to own. Perfect for shops or race teams that change wheels or brake components often. For shops you can measure wheel clearance and order the correct spacers the first time around (no wasting inventory or paying return shipping). Note: Kits purchased to Own are not returnable for refunds.
• Rent. Pay the full price but get $110 as a store credit when you return the kit. We keep a modest $19.95 fee for the service. Perfect for DIY and enthusiasts who only need the Test Kit once. Use your store credit to purchase your spacers (or anything else from our catalog).
