Benefits of a Wheel Stud Conversion Kit

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 beforehand 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 the 75mm studs. For 15mm, 18mm, 20mm, and 25mm spacers, the 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.

    Great for walking all day at work as well
    Size: X-Large, Color: (001) Black / Black / White
    I walk approximately 10 miles a day at work, in a manufacturing setting. On concrete with steel toe shoes. My feet have been begging me to change from the socks that I have worn for years. I have worn these other name brand socks for probably 10 years. So, change was obviously something I had to be pushed into. I got on Amazon and searched for training socks. I read the description. Glanced at the reviews. I decided to move forward with purchasing these. I could not have been happier. My feet began feeling better immediately. And the priced was very reasonible.

    LOVE THEM!!
    Size: Small, Color: (001) Black / Black / Castlerock
    LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!

    So will not write down your foot
    Size: Medium, Color: (001) Black / Black / Castlerock
    I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.

    Comfy and Stay Put
    Size: Medium, Color: (002) Black / Black / Halo Gray
    These socks are honestly great. They’re super thin and light, so once you have them on, you kind of forget they’re even there. No bulky feeling in your shoes at all. The best part is they actually stay on. I hate no-show socks that slide down after five minutes, and these don’t do that. The little grip on the heel really works, so you’re not constantly adjusting them all day. They’re breathable too, which is nice if your feet run warm. They dry fast and don’t get that gross sweaty feeling. And there’s no annoying seam on the toe, so nothing rubs or feels uncomfortable. Basically, they’re just comfy, stay put, and don’t cause problems — which is all I want from socks.
