The performance difference between forward and reverse rotations.
The slots are effective in both forward and reverse rotations. The reverse rotation has a higher friction level compared to forward rotation. But the downside is that the pad wear rate is higher for reverse rotation compared to forward rotation. Please look at the chart below to see the comparison between forward and reverse rotations.
The data above is based on our Z type pads. This test data is from testing on the street and race circuit. The values can vary depending on the pad material. Pad wear level also depends on the usage. At DIXCEL, we evaluated each disc’s characteristics.To achieve a high level of friction, we recommend the following setups. For Rotors with 6 slots, we recommend reverse rotation. For Rotors with 12 slots, we recommend forward rotation.
The two-piece brake Rotors come in 6, 8, and 12 slots. Please use the Rotors in reverse rotation NOT forward rotation. For one-piece Rotors with directional ventilation, please install in the forward rotation since reverse rotation will be harmful to the cooling effects. While slots provide greater friction coefficient, the amount of dust and noise may change in some cases.
