In ’83 we manufactured the world’s first ever grooved brake disc, which has since been developed into the range of styles that we offer today.
Every one of our discs is manufactured from the highest quality casts and steel billets before being heat treated and balanced by hand for the smoothest possible surface.
- Every blank cast passes stringent quality controls
- Precision facing by CNC turning machines and TAROX built machinery
- Perfectly level surface machined to a tolerance approaching 0.015mm
- Ground individually by a specialised operator, resulting in that distinctive shine
- Structural stress relieving heat treatment at the end of each machining phase

Foundation for excellence
We always start with the absolute highest quality raw materials. The bare cast iron rotors that are the foundation of any of all our performance discs are always European sourced from the best foundries and, where possible, 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
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
Each new application gets a custom designed CNC program for every TAROX disc design, to ensure any modifications do not affect structural integrity. For instance, when designing a program for our Sport Japan brake disc – 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 disc 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 disc is countersunk to prevent against cracking.
Our G88 has a unique look and amazing road performance. It features 40 radial grooves on each side of the disc which are channelled using a custom machine designed and manufactured in house. This allows us to achieve a surface that does not compromise pad life whilst offering the performance of a drilled disc and the structural benefits of a grooved disc.
Final balance and polish
The final stage and one that really sets a TAROX disc apart is the hand finishing. Before being shipped, each and every brake disc 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 disc developing lateral oscillation (run out). A perfectly machined part with a high shine and oozing quality is just the icing on the cake.

Although plain in appearance, the ZERO discs are far from an original disc. TAROX Zero discs are made from special high grade casts submitted to several levels of heat treatment. An outstanding resistance to high temperatures prevents warping and cracks. The final hand finishing leaves them incredibly smooth allowing them to mate to pads efficiently, increasing life of the disc and pad.
The ZERO has proved highly successful in both circuit racing – where regulations do not allow modified brake systems – as well as group N competition.
Regular use in international Endurance racing saw the Zero last up to twice as long as a regular plain disc.
The G88 is the most unique of our brake discs and unmistakably TAROX. The reason for this unique appearance is the custom built machinery, designed and made by TAROX to ensure the grooves on the G88 are like no other.
The G88’s grooves feature an edge to edge design, ensuring absolute maximum dissipation of heat, while incorporating a chamfered leading edge, which ensures that the life of the brake pad is not decreased.
The unique grooves allow the G88 to run cooler than any other performance brake disc tested against it. Its unique looks and unrivalled performance on the road have led it to be a firm favourite for street tuning since its conception in 1988.
As with all of the TAROX performance disc range, the G88 only uses the highest quality European high carbon TUV approved castings and features the unique TAROX finishing processes of heat treatment for strength and durability, hand finished balancing for a perfectly flat surface allowing for easy bedding-in and a perfect contact patch for maximum braking efficiency and a final, anti-rust treatment.
As the name implies the Sport Japan was originally designed for the Japanese market, where performance and tough looks are essential.
Sport Japan discs are one of the only aftermarket performance discs to still feature fully drilled holes, which is one of the most effective ways of venting hot gases from the brake surface. Although effective, this is an aggressive method of dissipating heat. To ensure ultimate performance and durability all Sport Japan discs feature countersunk holes strategically placed in order not to affect the discs structural integrity. This method is much more effective than a dimple, as the gas actually leaves the discs surface into the ventilation channels in the disc centre and away from the disc surface, ensuring the disc runs cooler for longer.
An additional 6 grooves on the braking surface act like a wiper, keeping the brake pad from glazing and removing excess dust while providing additional cooling. All Sport Japan discs are made from the highest quality high carbon TUV approved castings, and feature our unique finishing processes of heat treatment for strength and durability, perfect final balancing to within 0.01mm for a perfect contact patch and quick bedding-in and a final, anti-rust treatment.
The F2000 transcended from a racing specific disc into the road range. With the big power increases of modern day sport saloons and hot hatchbacks, combined with the increasing popularity of track days, there was a demand for a disc which could cope with high operating temperatures and gruelling conditions.
The F2000, first developed for use in touring cars over 15 years ago and often found in the TAROX range of big brake kits, has forged a reputation as the toughest performance aftermarket brake disc available.
Spiral grooves are the perfect compromise of cooling and integrity: the F2000 will feature between 7 and 9. As with all TAROX discs, the F2000 is manufactured using only the highest quality high carbon TUV approved castings and features the unique TAROX heat treatment for strength and durability, final hand balancing for the smoothest finish ensuring perfect contact and a quick bedding-in process and a final, anti-rust treatment.
