I think my mechanic meant the pad was bigger than the rotor; thus, not fully utilizing the surface of the rotor. He didn't say how much it didn't cover... this is something I wish I had asked...

See my picture I added to my previous post. The pad should be entirely on the surface of the rotor, however it will not cover the entire rotor's surface, but any mechanic should know that.

Something sounds fishy.

Thanks for the photo reference. I'll show it to him and see what he says. In theory it should work.. and if it does, this is the missing piece for the caliper upgrade for IS250 AWDs.

The setup I have is 350 rwd rotors, with 350 rwd calipers, shims etc. I had the shop trim the dust shields, but the bolts connecting the hub to the rest of the suspension were hitting on the rotor as well besides the dust shield and then I read about the whole knuckle assembly having to be changed in order to use this set up.

So all I need to do to make this work is use 350 awd front rotors and I should be ok?

If so does someone have a link to purchase some is350 awd front rotors, I cant seem to find them at sewell or anywhere?

You have a awd? Then get the awd rotor and caliper from the awd is350.... Or else you have to buy the hub and all that if u have the rwd and you want to use that for the awd...

I thought I would just need the awd rotor and can use the rwd caliper?

Link for the awd rotor?

Or can I use a GS 350 awd front rotor without modification?

IS350 RWD and AWD use the same calipers, all years. GS350 RWD/AWD are the same too.
IS350 09-12 USA RWD and 11-12 AWD use the same rotors.
IS350 06-08 USA RWD and 06-12 Canada RWD use the same rotors, but these are not the same as the AWD.

Thanks for all the info, so in short:
My 06 IS250 AWD will need a is350 AWD rotor, and only that rotor to make this work, no awd gs350 rotors will work?

so will the 09- 350 rwd and 11-12 awd rotors both fit the IS250 awd? or is this a completely different hub?

For an IS250 AWD, you should be able to use the following rotors:

09-12 IS350 RWD (USA-Spec)
11-12 IS350 AWD
06-11 GS350 AWD

Hi Jeff,

I have a 2010 IS250 RWD and will be upgrading to IS350 BBK.

1. How do I know which year of IS350 calipers are mine? The sale didn't mention the year or if it's for RWD. - Doh!!!!

2. Are the rotor size based on caliper or the hub? In other words, if my IS350 brake are from 2006, should I get rotors based on the 2006 (brakes) or 2010 (my model year)?

I notice that there are 2 different rotor models based on year of IS350 on http://ebcrotors.com/p-223-ebc-sport-rotors.aspx :

2010 IS350

Part Number: GD7529
■Front Rotor Diameter: 13.1"

2006 IS350

Part Number: GD7389
■Front Rotor Diameter: 13.1"

Any year or model IS350 calipers will work, they're all the same 06-12.

As for the rotors, it doesn't matter on the RWD, any IS350 rotor will work. Only if you had an AWD would it make a difference. The difference is shape of the cooling vanes where the rotor meets the hub, both styles fit fine on a RWD.
