APEX BMW stud and nut kit

The new and improved APEX BMW stud kits are the perfect upgrade for use with performance wheels. The studs are designed with an improved shoulder design that reduces stress points and prevents stud breakage – a problem encountered with many traditional solutions.

The studs include a 5mm hex socket for easy installation. The new model is also available with a bullet nose tip, which facilitates wheel alignment, especially in track driving.

With this kit, you can convert BMW's original wheel bolts into studs, making wheel installation safer, faster, and easier. The kit can be used with or without spacers, and installation is simple.

• 4-bolt kit: 16 studs + 16 nuts

• 5-bolt kit: 20 studs + 20 nuts

• Installation kit sold separately

• Studs and nuts also available separately

Advantages of the stud kit

It's hard to find a BMW track car that hasn't already switched to studs. The reason is simple: they are stronger, safer, and significantly speed up tire changes.

Even in a regular street car, studs make wheel installation easier. With wheel bolts, the wheel, spacer, and hub must be perfectly aligned before the bolt can be threaded into place. With studs, the wheel can simply be slid into place and tightened with nuts.

Without studs, the wheel can easily fall off the hub during installation. Studs keep the wheel in the correct position and greatly facilitate installation.

Extended studs also allow the use of various spacers without additional modifications:

• 75mm studs: for spacers 0–12 mm

• 90mm studs: for spacers 15–25 mm

Both lengths can also be used without spacers.

When using wheel bolts with spacers, different length bolts are always needed depending on the spacer's thickness. With a stud kit, one solution works in all situations.

Because the studs remain permanently in place, they also reduce wear on the hub threads. When changing wheels, only the nuts are removed, as in many other cars.
