※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.
