Sold as a set of four pads: two for each caliper, which is enough for both front or both rear calipers.
Click here for rear R4 brake pads for a 2005-2012 DB9 or V8 Vantage.
These pads have not been tested in brake systems with carbon/CCM rotors.
I highly recommend only using matching brake pads. That is, if you need to replace your OEM front pads and want to use the R4 pads, you should replace all the pads, even if the OEM rear pads are still okay.
Wear Sensors: These brake pads do accommodate the brake pad wear sensors.
2005-2012 V8 Vantage and DB9, front*
2017+ DB11, non-CCM rotors, rear
2019+ Vantage, non-CCM rotors, rear
* 2012 was a transition year for the DB9 and V8 Vantage. The DB9 switched to a completely different braking system with CCM (carbon) rotors and the V8 Vantage switched to a 6-piston front brake system. In each of these cases, these brake pads are not suitable for cars with the updated brake systems.
