Our new and improved APEX BMW wheel stud kits are the perfect upgrade for any set of performance wheels. We engineered these wheel studs with an improved shoulder design to eliminate stress risers that lead to stud failure in most other designs. These wheel studs feature a 5mm hex head for easier install, but our new design is now also available in a true bullet nose version. Use this kit to convert your 5 lug BMW from inconvenient lug bolts to stronger and safer wheel studs. These can be used with or without spacers, and are easy to install. 4 lug wheel kits include 16 studs and 16 lug nuts. 5 lug wheel kits include 20 studs and 20 lug nuts. Install kit sold separately. Studs and nuts can also be purchased individually. Click Here for installation instructions.
Try and find a BMW race car that hasn't converted to wheel studs yet with a stud conversion kit. They're stronger, safer, and improve pit stop times significantly. For non race cars, stud conversions still make wheel installation and removal much easier as you no longer have to line up the holes in your wheels, spacers, and hubs before hand threading a single lug bolt through. Simply slide the wheel onto the studs, and let go. With lugs, an unsupported wheel will slip off the hub lip and fall onto the ground. With studs, there is enough length to float the wheel in place and in proper alignment. Sitting on the ground with your feet under the car, and supporting the wheel with your feet while you try and line everything up is a thing of the past. Extended length wheel studs like these allow for a range of spacers to be used without any additional modification. You can easily use 3mm, 5mm, 10, and 12mm spacers with our 75mm studs. For 15mm, 18mm, 20mm, and 25mm spacers, our 90mm studs are required to allow for enough thread engagement. Either length kit can be used without spacers just as easily. When using lug bolts with spacers you are forced to purchase a different length lug for each width spacer as any spacer even 3mm thick is dangerous to use with the short thread OEM BMW lug hardware.. Why own a bucket full of lugs when a single set of studs can do it all? By remaining installed, studs will put less wear on the threads of your hubs. They guarantee there is enough thread engagement, as you can see how many threads were engaged during install. Wheel studs replace your OEM lug bolts by simply threading into your car's hub. Once installed they do not need to be removed when changing or removing wheels. Only the lug nuts are removed similar to many domestic and import vehicles.
