Clear BMW chassis

Please ensure your correct model is selected

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. Our original bullet nose studs are available in 78mm and 90mm overall lengths. The 78mm works great for cars that do not use a spacer (or a spacer smaller than 15mm). We recommend the 90mm length for cars that have a spacer larger than 15mm. These studs come with a black magnesium phosphate coating for excellent corrosion resistance. These studs are perfect for dual-purpose street/track cars. The studs are stronger and safer than wheel bolts and have a barrier against corrosion which makes them suitable for street use. For a dedicated race or track car, where wheel changes or pit stops are more frequent, check out our racing dry lube studs. Our studs are also designed and manufactured with the properly sized shank to work with a wider range of BMW wheel, nut, and brake rotor combinations. We intentionally avoid the extra large shoulders you see on other studs because they can interfere with some brake rotor hats. The extra-large shoulder can be too large to allow the rotor to pass through and drilling out the holes is required (not cool!) Our studs have the sufficient shank for the brake rotor without interfering.

17mm black lug nut to fit 12x1.5 thread wheel studs (common for most BMWs made before 2012). This is a super tough wheel stud nut in a standard 17mm size. The black finish is durable, corrosion-resistant, and stealthy so it blends in with dark-colored wheels. BMW designed their wheels to use a black bolt so more of the silver design 'pops' or is more eye-catching. These black wheel nuts preserve that effect. 17mm is the standard BMW bolt head size so you won't have to buy extra sockets. The seat is a standard diameter but may not fit all brands of wheels. If you have a small diameter bolt bore on your wheels, try our compact 19mm wheel nuts.

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.

These wheel studs are the same as our hugely popular Bullet Nose studs but with threads along the full length of the stud. This gives you more threaded area for tightening wheel nuts or allows the use of a closed-end wheel nut. These also have a more OEM appearance. Although these are a lower cost version of our Bullet Nose studs, they are every bit as strong, durable, and safe. The Bullet Nose is an upgrade because it's easier to install and almost impossible to cross-thread a nut.

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.

Threadlocker is essential when doing any work to your car, especially prepping it for the track. Loose bolts should never happen! If you are a do-it-youselfer, or do much wrench turning, then you know about threadlocker (generically known as "locktite" or by the brand name Loctite). You also know a little goes a long way. This small bottle of Palm Labs Turbo-Lock red threadlock is perfect for that small job -- or a few small jobs! This tube has 10 mL (0.34 fluid ounces) of high-temp, high-strength threadlocker. This bottle comes with two ways to apply: with a squeeze or with the included brush. There are just too many different uses for this, and no mechanic or DIYer, should be without some in his or her toolbox.

Red or Blue threadlocker? Red is the highest strength so use it when the fastener will not be removed regularly or ever again. The Red will need a great amount of force to break free and maybe even heat. Blue is the medium strength and will break free with hand tools. Use it for fasteners that need extra locking protection but will be removed / disassmebled on a semi-regular basis.

Palm Labs Turbo-Lock Series 13-OR Features:
  • color: red/orange
  • Anaerobic Thread-locking Compound
  • permanent
  • high strength
  • high temperature resistant
  • oil resistant
  • primerless
  • acceptable up to 20mm (3/4") bolts
    Equivalent or superior to Loctite 262.

    55mm is a very short wheel stud. Refer to our detailed measurements in the image below. You have to ensure that enough of the stud is sticking out from the hub to fit with: your brake rotor hat and wheel thickness, plus at least 10mm of nut engagement. For a longer stud, see our 75mm and 90mm full-thread stud.

    17mm lug nut to fit 12x1.5 thread wheel studs (common for most BMWs made before 2012). This is a super tough wheel stud nut in a standard 17mm size. The zinc finish is durable and bright so your eye catches it quick (important during fast pitstop tire changes). 17mm is the standard BMW bolt head size so you won't have to buy extra sockets. The seat is a standard diameter but may not fit all brands of wheels. If you have a small diameter bolt bore on your wheels, try our compact 19mm wheel nuts.
