• For the very best in a race-grade wheel stud, stop looking! These are the wheel studs that our race teams insist on (after years of trying every stud design on the market). MSI Racing specializes in hardware for motorsport use (NASCAR and IMSA) and other advanced industries. We tried them on our Grand-Am/IMSA racecars and were very impressed by the performance and durability of their designs. Race wins and championships can come down to the seconds of a pitstop. We could run any wheel stud in the world and we use these. 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 three overall lengths - 70.5mm, 80.5mm, and 90.5mm. All sizes are made with aircraft quality alloy steel and have roll formed threads for greater strength than cut threads. We use a dry film lubricant HM-30 coating containing Teflon & Moly over a manganese phosphate finish. Manganese is preferred over the more common zinc because it's better at reducing friction and wear to prevent thread galling. With the dry lube applied over the phosphate this is the best corrosion resistance we have seen in any wheel stud! Salt tests have shown this stud is superior to others in corrosion resistance. The dry lube helps the nut engage and glide over the threads for faster engagement without cross threading or binding. 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. 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.
  
  We configured these studs to have a 14x1.25 thread to go into the wheel hub. But the exposed stud has 14x1.5 threads. We did this because threading a nut is faster on 1.5 threads than a finer 1.25 thread pitch, which saved us time during pitstops. There are also more wheel nut options in 14x1.5. When you order our 14x1.25 studs make sure you also order the 14x1.5 nuts.

Enhance wheel replacement efficiency on your BMW with a stud conversion kit, facilitating quicker and easier wheel changes. This comprehensive kit includes:

• Conical Seat Lug Nuts (20)
• 75mm Wheel Studs (20)

The installation of these studs provides a permanent wheel-hanging solution, saving time and reducing hassle during wheel changes. By simply screwing in the supplied studs, you'll be ready to go.

Benefits of using wheel studs instead of wheel bolts:

• Some racing regulations mandate wheel studs for enhanced wheel-to-hub contact, ensuring added safety.
• Wheel studs accommodate various spacer widths, eliminating the need for custom bolt lengths when using spacers.
• Simplifies wheel installation; the studs act as wheel hangers while nuts secure the wheel in place.
• Reduces wear on wheel hubs as wheel studs remain in the hub, unlike constantly removed and installed wheel bolts.
• Facilitates quick and easy tire changes as wheel studs stay in place.

Note: Use thread-locking compound during installation and torque studs to 15Nm for optimal performance.

Upgrade your BMW's wheel system with this stud conversion kit for improved convenience and functionality.

Note: Thread-locking compound is recommended during installation. Studs should be torqued to 15Nm. These studs may be used with spacers up to 20mm.

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.

By moving your wheels a few millimeters each, you can give yourself enough clearance for proper wheel fitment and give your car a wider stance in the process.

ECS Tuning wheel spacers are constructed of high quality 6061-T6 aircraft grade aluminum and are specifically designed by in-house engineers and cnc machined to exact standards, ensuring the best fitment possible. By carefully measuring the OEM wheel hubs and bore dimensions, these spacers mount with minimal clearance to prevent any vibration, retaining the stock-like vibration free operation. 

This kit includes wheel bolts that are lab tested to meet or exceed ISO 898 class 10.9 mechanical and physical properties to ensure perfect fastening of the wheel to the hub with no issues or potential to snap under aggressive driving conditions.
