2. What is a stud conversion kit?
Wheel stud conversion has existed for multiple decades. They are a kind of special studs with both ends threaded, which convert your lug bolts fastening method to lug nuts. Many European cars (such as BMW, Mercedes-Benz, Audi, and Volkswagen…) use lug bolts to secure the wheels. A lug bolt features a threaded stem attached to a conical/ball seat that matches the wheel insert. Unlike lug nuts, lug bolts fasten the wheel and brake the rotor directly onto the hub. This makes changing the brake rotor easy but an added hassle of lining up the wheel and brake rotor when mounting wheels/tires. Wheel stud conversion offers an easy way to align the wheel when mounting. They make it more fluent to change wheels and save much time for you. It is a simple but high effective upgrade for your car.
3. Are wheel stud conversions safe?
As long as you use high-quality stud conversions, they are actually safe.
The wheel stud conversion kit offers an easy way to align the wheel, which makes it more fluent to change wheels.
4. What’s the difference between wheel bolts and wheel studs?
Wheel studs with lug nuts are mostly used on Japanese-made cars (such as Honda, Toyota). The studs are mounted in the hub and protrude beyond the brake rotor hat. This makes it easier to mount wheels without having to hold the wheel up to align the holes. In other words, they make mounting and dismounting wheels a fluent operation for you. The wheels are mounted using lug nuts, which are screwed onto the stud. This also allows you to install some really nice style of lug nuts.
Wheel bolts are usually used on European-made cars (such as BMW, Audi, Volkswagen). The bolts use a threaded stem attached to a tapered head or ball head that matches the wheel holes. They go through the wheel holes, straight screwing into the hub, fasten the wheel in the proper place. The only problem is that the brake rotor rotates freely when taking off the wheel. That means it is hard to realign the holes (since there are no mounted studs in the hub) when you hold the wheel up with your legs reinstalling the wheel and then threading the bolts.
5. What are the Pros of Stud Conversion?
Aesthetically, they penetrate the wheels, which provides a sporty and aggressive look. Meanwhile, if you’ve ever changed your stock wheels to aftermarket wheels, you’d know that there are various types of lug bolts. You may even find it hard when realizing your old lug bolts don’t fit on your new wheels.
If you have added wheel spacers, to meet proper thread engagement, the thread length of the wheel bolts should equal the length of stock bolts plus the thickness of the spacer, which means you need extended wheel bolts. Then wheel stud conversion is compatible with both ball and conical seat lug nuts, which is suitable for most factory or aftermarket wheels. They usually come with longer threaded stems. The lug nuts’ thread length is capable to adjust to get proper fasten, which allows for the safe use of different thickness wheel spacers. You don’t have to change to another set of extended wheel bolts.
