Blank casts used for TAROX discs are obtained from ISO 9000 and TUV certified specialist foundries.
Each casting is subjected to stringent quality controls, including sample testing, to avoid potential problems due to internal and external blowholes, cold shots, sand inclusions and other defects.

Different types of cast iron are selected depending on the final use of the discs, so that it can be chosen to put the emphasis either on strength rather than lightness, especially if the brake discs are used in competition.

All the blank castings are subjected to structural stress relieving heat treatment at the end of each machining phase. It is this process which underpins the quality of TAROX brake discs.

Facing is performed on CNC turning machines or on traditional parallel lathes for smaller batches.
Another distinguishing feature of TAROX brake discs is their perfectly level surface machined to a tolerance approaching 0.015 mm, achieved during the final finishing of the braking surfaces on grinding machines; each disc is ground individually by specialised operator resulting, in that distinctive shining unique look.
