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 (we make 3mm, 5mm, 7.5mm, 10mm, 12.5mm, 15mm, 17.5mm, 20mm, 25mm, and 30mm spacer thicknesses).

This kit is for purchase only. It's perfect for shops or racecars where changing wheels or brakes is common. We also have kits that are available for rent.

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.

Protect Your Wheels with ECS Tuning Wheel Lock Sets

Safeguard your valuable wheels with ECS Tuning Wheel Lock sets, providing an extra layer of protection against theft without requiring expensive alterations. Bid farewell to concerns about wheel security, especially after investing significant time in searching for the ideal wheels or painstakingly polishing each mesh spoke.

These wheel locks effectively replace one of your wheel bolts, ensuring heightened security and peace of mind. Each kit includes a special socket tool for convenient removal. With a factory bolt length of 38mm and a conical seat design, these locks are compatible with most aftermarket wheels. However, exercise caution and avoid overtightening or using air tools. Also, note that lock keys are specifically oriented to fit bolts in a single, precise position.

Elevate your BMW's security with the BMW Conical Seat Locking Wheel Bolt Kit. This comprehensive kit provides peace of mind by securing your wheels against theft. Engineered specifically for BMW vehicles, these locking wheel bolts offer a precise fit and reliable performance. Say goodbye to worries about wheel theft and enjoy enhanced protection for your BMW with this essential locking bolt kit.

• Enhances security for BMW wheels
• Precision engineered for a perfect fit
• Provides peace of mind against wheel theft
• Specifically designed for BMW vehicles

• 75MM, 85MM, or 95MM LENGTHS
• Dry film lubricant HM-30 coating containing Teflon & Moly over a manganese phosphate finish
• Innovative nut-starter and bullet shape radius that all but eliminates cross-threading
• Properly sized shank to work with a wide range of brake rotor, wheel, and nut combinations
• Heat-treated aircraft quality alloy steel
• Developed from over 20 years of top level NASCAR use
• These studs are installed using the traditional 'double-nut' method (one regular nut and one jam nut) with thread locking compound (red Turbo-Lock or similar).

Wheel studs are among the safest and most beneficial upgrades you can make on a track car. Not only are wheel studs safer than wheel bolts but they make changing wheels/tires much easier. One of the frustrating things about installing your wheels on the hub is that it's difficult to line up the wheel on the bolt holes. As wheels get larger but also heavier it's even more trouble. Add in a wheel spacer and the task is twice as hard. BMW does produce a wheel alignment pin for this purpose but if you're changing wheels often a stud conversion is the better way to go.

MSI Racing specializes in hardware for motorsports and other advanced industries and their wheel studs are some of the very best in the professional motorsports world. MSI is already a major supplier to teams in the top NASCAR categories and we tried them on our Grand-Am/IMSA racecars and were very impressed by the performance and durability of their designs. After testing them over the course of a few endurance seasons we decided to offer them to all of our customers as well. These studs are available in multiple lengthsand all sizes are made with aircraft quality material and have roll formed threads. The coating is a dry film lubricant HM-30 coating containing Teflon & Moly over a manganese phosphate finish. This coating process reduces friction and wear to prevent thread galling. Another benefit is that these have the best corrosion resistance we have seen in any wheel stud! A dry lube stud has the most corrosion resistance than a plain black coating because the lube is applied over the black phosphate coating. Salt tests have shown this stud is superior to others in corrosion resistance. Other features of our MSI studs include a large bullet nose nut-starter and a properly sized shank to work with a wider range of BMW wheel, nut, and brake rotor combinations.

These studs are the perfect choice for endurance racers, sprint racers, track-only cars, or even hardcore street cars. The bullet nose on this stud is deeper than other studs we have used. More of the stud protrudes through the open nut so that everything lines up better on the threads. This helps to eliminate the possibility of cross-threading or thread stripping. In addition, the shank has been machined for proper brake rotor alignment. The dry lube helps the nut engage and glide over the threads for faster pit stops without cross threading or binding.

Not all wheel studs are created equal. We don't take a manufacturer's generic wheel stud from their catalog and call it our own. Turner Wheel Studs are designed to our own specifications and manufactured for us exclusively. Beware of cheaper studs on the market! We have seen other studs similar to our own designs that are not a true BMW fitment. There are differences that we have ironed out over our years of selling wheel studs for the BMW market. Our stud prices may be slightly higher than the rock bottom prices on the web but we promise that it's a higher quality.
