No need to replace the existing wheel studs:
The DRM System is fitted to the hub with special nuts and it carries new wheel studs for the existing wheel-nuts.

Made of Aluminum

This set for 1 axel consists of 2 spacers, all needed special nuts and studs.

 

DRM Wheel Spacers are made from a proprietary aluminum/magnesium alloy which
is not only incredibly strong, but also very light (up to 70% lighter than a comparable
steel product) to minimize unsprung weight. DRM Wheel Spacers are then hard
anodized to ensure a tough, durable finish that is resistant to chipping, scratching and
oxidation. Wheel spacers move the wheel out from the hub, effectively widening the
stance of the vehicle and lowering its roll center. This simple modification increases
lateral stability, which in turn provides improved handling, greater safety and of course,
the sleek style you’ve been looking for.
