I have a 2004 2.5T and not sure what the rotor size is, but my question is, does it matter?
Seems like there are two sizes, 288mm (11.3 inches) and 305mm (12 inches), but is there some reason why you can't put 12 inch rotors on a car that came with 11 inch ones and vice versa?

The only thing I could think of was maybe the calipers are different.

How do you tell which size rotors you have without taking the wheel off and measuring the OD?

Calipers
Caliper brackets
PIA to switch
Pretty sure you have 305 mm with a turbo

Well it turns out the damn thing has the smaller brakes on it. I'm kinda pissed off at Volvo about that too, actually. Called Chris at FCP and it seems like its a bit of a hassle to get the brackets needed for the bigger rotor so I might just stick with the 11s.

Junkyards should be full of them. 2 bolts and a hose, not much hassle at all. Or you can call Erie or V&S, I bet they have tons of them.
