CAN ANYONE POSITIVELY CONFIRM THAT FOR THE 2010+ IS350'S, THE AWD AND RWD FRONT ROTORS ARE THE SAME

I know that for the 250's AWD/RWD are not the same, and the 2006-2008 is350 rotor are different BUT everywhere i go, including SWELL LEXUS, TIRE RACK, AUTO ZONE, ADVANCED AUTO, all have the same part numbers for the AWD and RWD models for 2010 and up

I tried to call the Lexus dealership parts department but they told me that the AWD and RWD OEM part numbers are different.

Can anyone POSITIVELY confirm?

There are 2 types of IS250 front rotors and 3 types of IS350 front rotors. They vary between years and models, as well as what country the vehicle was destined for.

IS250:
06-08 are all the same (28mm thick, non-directional cooling vanes)
09-13 Canada-spec are the same as 06-08
09-13 USA-spec are different than 06-08 and 09-13 Canada-spec (32mm thick with directional cooling vanes)

RWD and AWD makes no difference for the IS250.

IS350:
06-08 are all the same (30mm thick, outside-rotor centre vented hub, directional cooling vanes), will not fit AWD models.
09-13 Canada-spec RWD are the same as 06-08, will not fit AWD models.
09-13 USA-spec RWD are different than 06-08 and 09-13 Canada-spec RWD (inside-rotor cooling vane vents), will fit RWD and AWD models.
11-13 AWD are the same as 09-13 USA-spec RWD (inside-rotor cooling vane vents, more clearance for the AWD hub), will fit RWD and AWD models.


Part Numbers (IS250):

43512-30310 - 06-08, 09-13 Canada-spec (RH & LH Same)
43512-30320 - 09-13 USA-spec (RH)
43516-30010 - 09-13 USA-spec (LH)

Part Numbers (IS350):

43512-22260 - 06-08, 09-13 Canada-spec RWD (RH)
43516-22010 - 06-08, 09-13 Canada-spec RWD (LH)
43512-30350 - 09-13 USA-spec RWD, 11-13 AWD (RH, replaces 43512-30340)
43516-30040 - 09-13 USA-spec RWD, 11-13 AWD (LH, replaces 43516-30030)

I hope that helps!

Thanks man, thats what I figured. I've been trying to get a clear answer for this for the longest time but no body had one. Now I can order my rotors knowing that 09-13 IS350 are the same. Thanks
