20% MORE brake power! The Dixcel SD series rotors are for the users who want more braking power and better disc appearance when compared to their standard disc.
- Slots increase brake performance by up to 20% according to simulated testing.
- 6 slots is the standard for SD brake rotors. The 6 slot pattern was selected after careful examination of factors such as pad wear, noise level, and gas ventilation.
- For the 6 slot brake rotors, reverse rotation (slots pointing forward) is recommended for best brake performance.
- High carbon material is used for sports cars and vehicles with high brake loads to improve durability compared to conventional products.
- Slots are designed to rotate in a reverse direction to gain better "shaving effect".
- Offset slot pattern on outer/inner side of brake rotors reduces brake judder.
12 slot version is available upon request as an option.
The recommended slot direction is Reverse rotation for 6 slots and Normal rotation for 12 slots.
Anti-corrosion protection of the rotors will not completely prevent corrosion from occurring. Since the rotors are made of cast iron, it is impossible to completely prevent corrosion. Please be aware Dixcel will not offer any exchanges/refunds for corrosion of rotors.
Sample photo, actual product may vary. Not all products have ventilation fins.
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.
Test data comes from street and race circuit testing. The values can vary depending on the pad material. Pad wear level also depends on the usage. Dixcel evaluated each disc's characteristics. To achieve a high level of friction, Dixcel recommends the following setups. For rotors with 6 slots, Dixcel recommends reverse rotation. For rotors with 12 slots, Dixcel recommends 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.
