Turner Motorsport's five years of endurance competition has taught us many things. One was that not all lug-nuts are made the same. While the standard nuts that we sell are great for daily drivers, HPDE events, and club racing, a beefier and more durable nut was needed for the 3-hour, 6-hour, and 24-hour professional endurance races. During the 24 Hours of Daytona, our crew guys made over 80 tire changes in NASCAR-style pitstops. That kind of abuse from air guns and fast work required the "next level" of lug-nut. These nuts are a high-grade steel with a chrome coating and they incorporate several innovative features. The wheel-side of the nut has recessed threads so that the nut has to be square to engage the threads. Without the recess, it's far too easy to start the threads with the nut being crooked. The 19mm head of the nut is slightly rounded to help the socket find its position. The chrome plating that we use is reasonably durable without being excessive. With too much coating, the chipped and worn coating fragments can end up in the threads, leading to all sorts of trouble. Anyone who has used nuts repeatedly knows that the coating is not going to last forever. The constant abuse from air guns will chip it all away. So why add weight and the potential for disaster with excess coating? We did away with most of the danger from that with a lighter coating that still resists the tough environment of the track. Features: Developed for our Grand-Am / Continental race team High grade steel to withstand the extreme abuse of air guns and race conditions Bright chrome plating to help tire changer zoom in on their target quickly and accurately Minimal plating won't result in excess coating wearing off and "gumming up" the threads 19mm hex to prevent rounding off Rounded top for fast socket engagement Recessed threads to aid in fast nut-to-stud alignment without cross threading We recommend using with Turner Motorsport bullet nose dry-lube wheel studs Price is per nut.

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.

Priced per nut.

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.

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.

Sold per stud.

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.

19mm compact lug nut to fit 12x1.5 thread wheel studs (common for most BMWs made before 2012). This wheel nut has a reduced outer flange for a more compact and minimal fitment. On many wheels, the hole for the lugbolt or lugnut is a very narrow diameter. Not even the stock lugbolt will fit through and these wheels often come with their own lugbolts. Then when adding studs to the car the options for a small diameter lug nut are very limited. We ran into this problem over and over and finally found a solution! These compact lugs have all of the material of a 19mm nut but without the flange of a standard wheel nut. For this reason we do not recommend using these on a wheel that normally takes a standard bolt seat (the seat is very important to the strength and integrity of the design). But for wheels that are designed to use a small seat, these are the solution! Bright and durable zinc finish makes them easy to spot during fast pitstop tire changes.

Priced per nut.
Thin-wall 19mm socket may be required depending on your wheel design.
