ECS Tuning is proud to offer extended wheel bolts individually or with our spacers that are matched to take the guesswork out of correct fitment. Our bolts are designed to meet ISO 898 class 10.9 mechanical and physical properties. This is a very strict standard that specifies material properties, hardening and tempering requirements, and proof load strength requirements. Furthermore, our fasteners have been lab tested to verify that they meet class 10.9 requirements.

Bolt specifications:

• Diameter - 12mm
• Thread Pitch - 1.5mm
• Length - 50mm

*When installing wheel spacers, add the size of the spacer to the length of the OE wheel bolt for proper fitment (ex. 27mm Length OE Wheel Bolt + 15mm Wheel Spacer = Require a 42mm Length Bolt)

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.
