BONOSS Forged Grade 12.9 Wheel Bolts M14x1.25 for Mini Cooper S (2)

A better style! Last Monday, this Mini Cooper S installed BONOSS Forged Grade 12.9 Wheel Bolts, M14x1.25 together with new OZ wheels (Ball Lug Seat). Custom aftermarket wheels can not only add a personalized style but also enhance the handling performance of your vehicle. Therefore, when changing wheels, you can choose some non-original wheels according to your needs. Although many aftermarket alloy rims are designed to use your car’s stock lug nuts or wheel bolts, there are others that require new hardware. It can be something as central as the differences in the rim’s lug seat type, or something as simple as shorter heads of the lug bolts to fit the wheel’s center caps. (Thanks IG PERFORMANCE for supporting.)

How to confirm the seat type of Mini Cooper lug bolts for your new wheels? There are conical seat, ball seat, flat seat, etc. A 60° Conical Seat is the most common and is found on most aftermarket wheels. But every wheel is different, so please take a check to your new rims. For example, these OZ wheels are designed with a ball lug seat. Typically, for the factory wheels, the seat type of the lug bolts must be the same as the factory wheel bolts. For the aftermarket wheels, the seat type of the lug bolts must be the same as the type of the aftermarket wheels. It is essential that the Mini wheel bolts seat and the wheel lug seat match. Otherwise, the wheel bolts would be bent or damage the wheel.

How to Install Mini Cooper Wheel Bolts Safely?

The Mini Cooper wheel bolts need to be installed correctly, and they also must be properly torqued to manufacturer-recommended torque specs. This means making sure the lug bolts, wheel, and hub are secured enough to where they don’t get loosen. Untightened lug bolts (the clamping force is not enough) or overtightened lug bolts (the wheel bolt has been stretched past its tensile strength limit, so the clamping force has gone away) will cause most Mini lug bolts failures. Find a suitable balance in the level of tightness and the stud will remain strong, providing the greatest possible force to lock the wheel to the hub. This ensures the wheel bolts safe.
