EBC BSD Series Slotted Brake Rotors (BSD972)

EBC ‘BSD’ rotors employ bi-directional grooves designed to improve cooling to the central band of the rotor annulus, the region of the rotor which always runs hottest. Several grooves in the braking surface allow gasses and wear debris to be quickly evacuated from the braking zone, reducing brake fade and helping to maintain a smooth braking surface.

The higher groove count of BSD rotors vs. other EBC grooved rotor designs increases bite during initial brake application and results in a more responsive braking action. Together, BSD’s improved cooling and higher bite make BSD rotors well-suited to high-performance vehicles which are routinely driven spiritedly on the road or driven on track.

EBC BSD brake rotors, like all EBC 1pc brake rotors, are cast from a high-carbon G3000 rotor alloy, boasting excellent thermal capacity and high resistance to both warping and cracking, even when pushed hard on track. Unlike some other manufacturers, EBC sees no benefit in offering a ‘lower-performance’ or ‘low-carbon’ brake rotor range, since the use of poor metallurgy can decrease rotor life and performance yet shaves mere cents off the manufacturing cost.

The outstanding quality of EBC’s brake rotors is evidenced by the fact EBC Brakes is one of the first and only aftermarket rotor manufacturers globally that has both TUV and R90 approvals on their brake rotor range. This is in stark contrast to some other brake rotors available in the marketplace originating from the far-East, which often aren’t approved to TUV, R90 or indeed any other internationally recognised quality standard. EBC’s commitment to product testing means EBC’s brake rotors are fully compliant with ADRs and thus legal for use on public roads in Australia.

Every EBC rotor is machined using a ‘twin-turning’ process which guarantees near-perfect parallelism. This process reduces the likelihood that Rotor Thickness Variation (RTV) could manifest on the vehicle, which could otherwise create brake judder. Machined rotors are then run-out tested to ensure they meet EBC’s strict tolerances. Finally, every finished rotor is first Geomet® coated to protect all surfaces from corrosion, then rotors are additionally sprayed with an advanced anti-corrosion black coating to further protect visible non-contact areas from unsightly rust for an extended period after installation. This double-finishing process gives EBC brake rotors maximum protection from corrosion.

NOTE: The higher slot count of BSD rotors can lead to increased intermittent rotor noise, caused as each slot passes under the brake pad. Whilst this is only faintly audible in most cases, customers who prioritise silent braking should consider opting for USR rotors.
