I started to install a set of EBC Blue pads (for light track use) and planned to order some EBC Reds for street. The front pads fit perfectly, but the rear pads don't fully sit on the brake rotor. After talking with EBC and taking measurements, they still believe it is the right pad, but I'm curious for others who have installed aftermarket rear pads, if their experiences are the same.
The inner diameter of the rotor is where pad that hangs off by around 1mm.
The reason for this is because the holes for the caliper pins are ~1-1.5mm offset compared with the OEM pads. The tension on the metal spring clip is also less than OEM partially due to this offset.
Lastly, the EBC pad has a slightly larger pad surface towards the outer diameter of the rotor. This actually accounts for the 1mm offset of the caliper pins and keeps the pad sitting mostly in the same space as the OEM pads did - at least on the outer edges of the rotor.
At the end of the day I think I'll still try to run these pads as I don't think they'll create a lip on the rotor, but how it might cut unevenly into the pad will be interesting to observe.
Here's measurements I took between the OEM Brembo pad (top) and the EBC Blue pad (bottom).
If there's insights anyone can offer about their experience and how their pads sit on their rear rotors, that'd be helpful to me. Cheers!
