I'm sure all UK XC90's have 17" disks 7 seats and 4WD, and the 5 seat and 2WD versions were never sold in the UK, so unless your car is an import it should be 17".

Check with your dealer, I like a lot of others would recommend only using Volvo/ATE parts for the brakes. Your choice obviously, but some of the options that ECP, GSF and others offer for the UK are really nonsense for the versions that were offered in the UK.

Check with your dealer and VIN number for the correct parts, or carefully measure the rotors.
