Product Description

EBC’s grooved & dimpled ‘GD’ series brake rotors have all the benefits and aesthetics of a cross-drilled rotor, without any of the drawbacks. 3 wide-aperture grooves continually sweep the braking zone, allowing any gasses and debris particles forming at the pad-rotor interface to be effectively vented away. This helps to reduce the onset of brake fade in addition to preventing any trapped debris leading to ribbing/scoring of the braking annulus. 

Additionally, several dimples allow further venting of built-up gasses, but crucially without cross-drilling all the way through the rotor's cheek facings. Cross-drilling creates localised stress points and anyone who’s seen cross-drilled rotors that’ve been driven hard will be familiar with heat-cracking that always originates at the cross-drilled holes. That’s why EBC dimples the braking surface and doesn’t cross-drill.

Together the grooves and dimples result in a higher bite during brake-apply, giving a more immediate response that is particularly beneficial for spirited driving.

EBC GD 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 poorer 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: Customers should be aware that any rotor which has grooves in the braking surface will produce faintly audible intermittent noise during braking. Customers who want a grooved rotor but want to keep rotor noise to a minimum should consider opting for EBC’s USR grooved rotors.
