Upgrade to wheel studs from bolts for an enhanced connection and easier wheel installation. Racing entities often require wheel studs for better wheel-to-hub contact, offering improved confidence during high-speed performance. Turner Motorsport's wheel studs are designed to accommodate various spacer widths effortlessly, simplifying the setup process. Discover why this switch from bolts to studs can make a significant difference:

• Simplifies spacer usage with a single application designed for various spacer widths
• Wheel studs act as a wheel hanger, easing wheel installation
• Reduces constant wheel bolt removal, minimizing wear on wheel hubs
• Facilitates quick and easy tire changes as the studs stay in the hub
• Recommended torque of 15Nm with thread-locking compound during installation
• Compatible with spacers up to 20mm in size

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).
