Explore Brake Rotors

Foundation for excellence

We always start with the absolute highest quality raw materials. The bare cast iron blanks, that are the foundation of any of all our performance rotors, are always European sourced from the best foundries and, where available, using a cast with the highest possible carbon content. From this base we can then apply processes which we have been perfecting for 33 years.

Our first process is always heat treatment; known to offer big improvements to how cast iron behaves. The benefits are great but so is the time-cost and infrastructure involved, and TAROX unique in this approach.

What the metal industry experts say about the benefits of
heat treatment:

The heat treatment of gray irons can considerably alter the matrix microstructure with little or no effect on the size and shape of the graphite achieved during casting.

‘’Gray iron is normalized by being heated to a temperature above the transformation range, held at this temperature for a period of about one hour per inch of maximum section thickness, and cooled in still air to room temperature. Normalizing may be used to enhance mechanical properties, such as hardness and tensile strength’’- Source

‘’Normalizing heat treatments for castings:  The process can be employed on cast products to homogenize grain structure, improve machinability and response to subsequent heat treating processes. The normalizing process is commonly applied to carbon and alloy steel castings in order to refine grain structure and produce a more uniform distribution of carbon content throughout the material after the casting process. During normalizing, castings are typically heated to a temperature slightly above the austenitizing temperature to promote atomic mobility that enhances homogenization of the steel. The final result is a casting that will machine more easily and have more uniform micro-structure. Normalized castings respond to heat-treating better and have more uniform mechanical properties.’’ – Source

CNC work

Each new application gets a custom designed CNC program for every TAROX rotor design, to ensure any modifications do not affect structural integrity. For instance, when designing a program for our Sport Japan brake rotor – which features fully drilled holes – it is essential to not fully drill where a hole may foul an internal structure vane while ensuring as many holes as possible, allowing air to flow in between the channels of the internal cooling structure. This is again a time consuming and costly process and one of the reasons performance rotor manufactures only use a dimple – which does not allow air to move from the surface in to the internal cooling channels. Any drilled hole on a TAROX rotor is countersunk to resist against cracking.

Our G88 has a unique look and amazing road performance. It features 40 radial slots on each side of the rotor which are channeled using a custom machine designed and manufactured in house. This allows us to achieve a surface that does not compromise pad life while still offering the performance of a drilled rotor and the structural benefits of a slotted rotor.

Final balance and polish

The final stage and one that really sets a TAROX rotor apart is the hand finishing. Before being shipped, each and every brake rotor is placed on a specialist machine which perfectly balances it to 0.001 – ensuring the flattest disc on the market. The process of achieving a perfectly flat surface not only enables the brake pad to bed in quickly and more effectively, but reduces chances of the rotor developing lateral oscillation (run out). A perfectly machined part with a high shine and oozing quality is just the icing on the cake.
