The Stud Conversion Kit is a welcome product that changes the way most European car brands fix their rims, and in addition to the change in mounting method, the stud conversion kit also offers a number of additional benefits to customers. The reason why most BMW Mini Cooper owners choose this product is that the installation of wheel spacers requires the purchase of extended lug bolts and, after purchasing a set of expensive aftermarket lug bolts, they can only be used with wheel spacers installed. The wheel spacers can be removed, but a set of extended lug bolts cannot be used with the original offset, the long threads prevent the lug bolts from screwing into the bolt holes completely, and ultimately the rim cannot be fixed. As you can see, the cost-effectiveness of purchasing a set of extended lug bolts is not comparable to that of a stud conversion kit.

How Much Wheel Spacers Can Stud Conversion Kit Fit?

The length of the stud conversion kit is mainly determined by the length of the stud. The BONOSS Titanium Stud Conversion Kit is available in a single stud length of 75mm, which is the standard length, but BONOSS also offers custom lengths from 75mm to 85mm. At the standard length of 75mm, the BONOSS Titanium Stud Conversion Kit can be used with Slip-on hub centric wheel spacers of less than or equal to 20mm. Some customers may be concerned that this length will not ensure safe driving, below we will calculate a safe stud conversion kit length using the BMW Mini Cooper hub data and BONOSS 20mm hub-centric wheel spacers as an example.

The Mini Cooper F56 hub data is PCD:5×112, CB:66.5, Thread Size:14×1.25, Bolt length:27mm, and Wheel spacer thickness:20mm. We know that the safe length of the extended lug bolts should be 27mm+20mm=47mm, and the length of the stud conversion kit is 75mm. The length of the stud is 75mm, and the calculation result is 75mm>47mm. in addition to this, you also need to add the rim bolt hole depth, as this BMW Mini Cooper uses a BBS aftermarket rim, so in the case of 47mm+bolt hole depth≤75mm allowed to install.

In the comparison chart, we can clearly see that with and without wheel spacers fitted, the head protrusion of the stud conversion kit is quite clear. Some customers also prefer not to fit wheel spacers, leaving the stud conversion kit protruding, which is one of the features of the stud conversion kit is that it offers an aggressive rim style. With wheel spacers fitted, the fitted stud conversion kit still retains part of the unthreaded section, which is a special design by BONOSS for 20mm wheel spacers, and as mentioned above BONOSS offers custom lengths of up to 85mm in the longer stud conversion kit.

However, BONOSS has taken into account the fact that 20mm and above wheel spacers are not suitable for use with the slip-on design, so BONOSS 20mm and above wheel spacers are generally designed with the stud-on design to ensure the safety of the wheel spacers. However, this does not prevent customers from purchasing a 75mm stud conversion kit to match the 20mm wheel spacers.

Can Stud Conversion Kit Fit My Car?

The BONOSS Titanium Stud Conversion Kit is designed with a car side and a wheel side, the car side end is fitted to the hub lug bolt holes. BONOSS has taken into account the fact that the majority of customers choosing the stud conversion kit are from Europe brands and has designed the kit with three types of thread data, M12x1.5, M14x1.25, and M14x1.5, which cover the main European brands, including BMW, Mercedes-Benz, Audi, Porsche, Ferrari, Renault, etc. If you are unsure of the data you can contact BONOSS customer service for assistance when selecting a stud conversion kit.

At the wheel size end, there are two thread options, M12x1.5 and M14x1.5, which take into account the lug nuts that may be fitted to the customer’s aftermarket rim. In theory, the BONOSS Titanium Stud Conversion Kit is compatible with all European car data, but if you have a special thread data customization or length customization you can ask for help from BONOSS customer service.
