HD(plain disc) / HS(6 slot)
In pursuit of higher stability
  • The heat treatment stabilizes the bonds between the elements in the structure of the cast iron. This prevents disc distortion and strain which is common immediately after installing new discs.
  • The treatment also optimizes the surface hardness, which improves brake response.
  • Higher performance can be achieved by using the HD discs along with the Z type or R series pads.
  • We recommend this disc for advanced drivers who require/want more braking stability.

※The heat treatment does not directly improve brake performance. The heat treatment increases the disc resistance against strains and thermal cracking. It also helps maintain stable brake performance for a extended period of time.

※The surface of the heat treated brake discs has a burnt colour. Once it is used, the burnt surface will be removed by the pad, and changes back to the colour of normal cast iron.  Please be aware that the effect of the heat treatment of the disc will not disappear even if the surface colour changes.

※ 12 slot versiog (HST type) is available upon request as option.
The additional charge of 12 slots is JPY6,000.

HD(plain disc) / HS(6 slot)
Is it better to change the brake pads and brake discs at the same time?
HDtype グラフ
  • The above chart represents evaluation values of our product in 100 phases in comparison with genuine rotors of the test model. Values of genuine rotors show 50.
  • The values above should be only used as a reference to better understand the performance differences.
  • Higher values signifies the performance increases when compared to the standard disc.
The DIXCEL HD series is for race circuit drivers and race enthusiasts, who need higher heat stability compared to the standard disc.
Cutting for balancing

Cutting for balancing

All DIXCEL brake discs are checked for balance to prevent vibration.
Correction of the balance is done by milling/cutting out the side of brake discs.
This is a method taken by car manufacturers' brake discs.
