Disc Friction Rings
Our 320x33mm R-Line race discs are cast from a proprietary high-carbon cast iron alloy that provides excellent durability and stability under the high thermal loads experienced under off road race conditions. The discs feature 68 x curved, directional cooling vanes. The design significantly increases cooling vane surface area and air-flow when compared to factory / OEM disc designs, resulting in vastly improved cooling.
The slot pattern chosen for our R-Line discs is our well-proven “RS” slot pattern that efficiently removes of sand, mud and water (commonly experienced under off road race conditions) as well as carbonised pad material from the disc / pad interface. The slot pattern also provides good bite and release characteristics.
Every single Powerbrake R-Line disc is measured for run-out and disc thickness variation (DTV) using Swiss measuring equipment. When it comes to QC, there is no batch or statistical quality checking of Powerbrake discs. Every single disc is measured. Our machining tolerances are up to three times tighter than the industry norm.
