The Porsche 918 Spyder is an innovativ supercar and also the strongest and fastest serial hybrid in the world with a total power of 887 hp. A 4.6 l V8, combined with an electric motor on each axis enables the two seater to accelerate from 0 to 100 km/h in just 2.6 seconds. Due to an intelligent 4 wheel drive system with torque vectoring, ideal traction can be established in all situations.

Apart from the motors another component with high significance concerning the longitudinal acceleration are the brakes. In order to guarantee the necessary deceleration, carbon ceramic brakes are installed by default. These can withstand higher temperatures than conventional brakes with steel disks. Porsche chose a yellow-green paint on the brake callipers of the system, placing a special accent on the parts.


The shown ensemble in honor of the 918 Spyder consists of a pair of three part cufflinks, as well as a three part tie bar.
The important parts of caliper and disk are made from Silver. A yellow-green coat of color is applied to the calipers. Brake disks are also painted.
Represented in the model are also holes, colling channels and tiny bolting of the disk as well as a caliper with pressure cylinders and delicate hydraulic pipes.. Due to a bearing supported bolting with industrial parts a a movable model is created with spinning disk.

In order to guarantee an effective cooling, seperating walls inside the ventilated disk are designed to be alternately shorter and longer in real brakes, which is also featured in the jewelry model. This method is done in order to prevent the cooling channels' cross section from becoming too small towards the disk's center.
Showing an accurate depiction of the special efficient geometry from the 918 Spyder brakes is made possible by an actual section in the brake disk, that is present only on the tie bar. The back plate is sanded down in this area to expose the inner geometry.

Multi Part

Main theme of the piece is an assembly of the parts rotor (disk) and stator (caliper) with a special type of bearing, in order to create a movable and functional object. This is done by using industrial hex key bolts combined with the precious jewelry parts from precison casting and elastic parts.

The materials for the painted parts is cast 925 Sterling Silver.
Only the cufflinks' backing as well as the tie bar are made from brass which is plated with rhodium. This material choice creates an elegant and high contrast appearence for the highly sophisticated pieces. Furthermore cufflinks and tie bar obtain a uniform design.
