Crack resistance When a one-make series Honda DC5 Integra is driven at 2min 10sec/lap on the Motegi race circuit Hairline cracks occur on the braking surface after 1 hour of use. Hairline cracks occur on the braking surface after 2 hours of use.
When an street legal Honda DC5 Integra is driven at 2min 20sec/lap on Motegi race circuit Hairline cracks occur on the braking surface after 2 hours of use. Hairline cracks occur on the braking surface after 5 hours of use.
Judder resistance When a one-make series Honda DC5 Integra is driven at 2min 10sec/lap on the Motegi race circuit Minor juddering (vibrations) occur after 1 hours of use. Minor juddering (vibrations) occur after 2 hours of use.
When an street legal Honda DC5 Integra is driven at 2min 20sec/lap on Motegi race circuit Minor juddering (vibrations) occur after 2 hours of use. No juddering (vibrations) occur after 4 hours of use.

 

 

  • ※The comparison test above was done using a non-heat treated disc by another manufacturer and our heat treated HD disc. 
  • ※All of the testing above was done on the Twin Ring Motegi race circuit.
  • ※The data values above can vary depending on the conditions (weather, pads used, vehicle set-up, driver, lap time).
  • ※The data values should only be used as a reference to better understand the performance differences.
