MAZDA MX-5 MIATA EBC RK Series Premium OE-Style Front Rotors RK7392 - 2006-2015
EBC adds value to its products by strictest quality controls and specifications and a 100% run out and dimensional check, including element analysis, surface finish and hardness tests on every batch and runout inspection . All sport rotors are slotted and grooved at the Las Vegas facility of the USA operation or at our new Northampton rotor facility employing 32 staff which has recently been enhanced to have its own QC department, machining and testing facilities and a new Nitrotherm anti corrosion coating plant.
We also do all we can to embrace US employment and in our US facilities we employ 14 people in our rotor machining facility alone.
All EBC Premium Brake Rotors or discs are cast to a material strength of 150 N/m2 with a tightly controlled surface hardness variation less than 20 HB and are precision CNC machined to a surface tolerance of less than 0.05 mm. That is two thousandths of an inch. For this reason EBC recommends a maximum runout of fitted rotors of 0.1 mm or .004 inches (4 thousandths) TIR which means total indicator reading on a dial gauge.
