Determining rotor size on 2004 XC90 Topic is solved

[ggleavitt]

Thought to revive this thread for a sec, had posted a photo link on another site, no reason it cannot also be on here as well (MVS is better for me since I can post photos directly):

Rotor photos from my '05 and '08, 316mm and 336mm respectively. Rotor with more fins is the 316, less fins is the 336mm. Rear rotor is the same on every car. These are OE rotors. 328mm rotor photo if anyone has one with details to close this out for visuals.

OE Part Numbers-
F- 316mm (31423325), 328mm (31400893), 336mm (30657301)
R- 308mm (31471824)

Edit 1/15/19- add OE PNs
