Hub Extenders are the solution that no one else has! BMW wheels must fit on a hubcentric lip to be securely (and safely) mounted to the hub. But with a 3, 5, 8, or some 10mm spacers on a lip measuring no more than 11mm that presented a huge problem - there would be no lip left over for the wheel to rest on! As one of the world's leading BMW tuners and race teams, we came up with a way to extend the lip and get back the lost surface area for the wheel to safely mount on. Our Hub Extenders are the first of their kind.

Hub Extenders fit where the stock dust cap is usually fitted on the front wheel hub. Pop out the dust cap and tap the Hub Extender into its place. It becomes an extension of the original lip. These will only work on the front hubs of the cars listed below because the rear hub is tapered inside (narrows down). These will not work with Xi AWD models because the front axle shaft protrudes through the hub. With Hub Extenders in place you can use nearly any flat wheel spacer - 3mm, 5mm, 7.5mm, 10mm, or possibly more without worrying that the wheel will not be securely seated. This is perfect for wheels that have chamfers on the back of the wheel that don't match up to existing spacers (Kosei K1 spacers for example).

Turner Hub Extender Features --

+ hub extension makes flat spacers a true hubcentric fitment
+ precise tolerance fitment thanks to CAD process and CNC mill machine
+ aerospace grade aluminum  light weight but very strong with a high resistance to corrosion
+ additional military-spec hardcoat for further corrosion resistance
+ stealthy black color with laser engrave Turner logo
+ Turner Motorsport track and street tested!
+ Made in the USA

Wheel Limitations. Special consideration needs to be taken since wheel design and manufacture differ from brand to brand. The key dimension is the dept of the center bore. Some wheels won't work with larger spacers and a Hub Extender because of the additional protrusion into the center bore. Please measure your wheel to make sure it can accommodate an extra 2.5-5mm of hub extending into the center bore. Click here for a diagram.

Hub Limitations. BMW has multiple hub designs but not all are compatible with our Hub Extenders. The inside lip of the hub must be flat and smooth for at least 13mm (the depth our Extender fits into the hub). Some BMW hubs have a bowl shape or have tapered inside walls which will prevent the Hub Extender from seating all the way. Remove the hub dust cap to check before opening your Turner Hub Extenders.

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).
