Porsche & Precision: Porsche Club Latvia visits AN riepu centrs
On 8 November, Porsche Club Latvia visited AN riepu centrs: a Central Lock adapter demo, diamond cutting, polishing and powder coating of wheels.
How do you mount a Porsche wheel with a Central Lock fitting on workshop equipment? What is the difference between diamond cutting and polishing, and what does wheel refurbishment involve? These were the topics of Porsche & Precision, an event held on 8 November 2026 at the AN riepu centrs workshop at Dzirkaļu iela 44 in Riga.
The event was organised for Porsche Club Latvia members and specially invited guests. Its purpose was to introduce wheel finishing technologies and offer a closer look at the work that customers rarely get to see.

In focus: our Central Lock adapter
The main topic was the adapter developed by AN riepu centrs for working with Porsche wheels that use a Central Lock fitting.
These wheels use a single central fastening rather than several conventional wheel bolts. Mounting them on workshop machinery therefore requires a suitable solution. Our adapter is designed to centre the wheel accurately and hold it securely.
The programme included an adapter demonstration, with a wheel mounted on the rig and an explanation of the process. This helps show why both the equipment and the correct working procedure matter when handling Central Lock wheels.
However, being able to mount a wheel on a machine does not in itself mean that it can be repaired. Its condition and the manufacturer's requirements must be assessed before any work begins.
Diamond cutting, polishing and powder coating
The programme covered several wheel finishing methods, giving guests an opportunity to understand how they differ.
Diamond cutting involves precisely machining the front face of a wheel on a lathe. This creates the distinctive metallic finish that highlights the wheel's design and contrasts with its painted sections.
Polishing is a different process, focused on the smoothness and shine of the metal surface. The programme included an introduction to polishing an entire wheel to explain how this finish is achieved.
The powder coating presentation covered renewing a wheel's coating and changing its colour. The final result depends on surface preparation as well as the chosen shade.
The programme also introduced metal spraying technology and its use in treating suitable types of surface damage.
Why should car owners understand these processes?
Choosing wheel refurbishment involves more than deciding on a colour or level of shine. The wheel's existing condition, its original finish and the methods permitted for that particular wheel all need to be considered.
A workshop visit offers the opportunity to discuss these questions where the work takes place. The programme allowed time for this alongside technology presentations and informal conversations about Porsche and cars.
Porsche & Precision was designed to bring car enthusiasts closer to the day-to-day work of wheel specialists and help explain what goes into the appearance of a refurbished wheel.
