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 brake pads for a 2005-2012 DB9 or V8 Vantage.
Click here for front brake pads for a 2nd century car (DB11 or Vantage) with iron rotors (non-carbon/CCM).
These pads are not suitable for brakes 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-S 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.
