Yours is the 350 with F-Sport package rite? Didn't change the suspensions or anything?

Seems like something is off..

For me even thou it's a 250 with F-Sport package this is what I have and do not have problems. Just normal scalloping on the outer edge.

-0.61 degrees for both front left and right for camber.
0.8mm toe for both front left and right

Seeing you have a brand new 2011 model and it is pre-maturely wearing tires I'd take that knowledge back to the dealership. When I got my `06 350 sports pkg in April `11 my 350 needed tires ASAP. Not only bad weathering on the sidewalls...but the OE Dunlops that were on it were also wearing on the inside more as well. Car was completely stock and never been in an accident.

I recently discovered it's a common problem with the IS. I'm not sure if the specs are the same on my 06 as they are on a 2011 F Sport. I did a lot of reading on CL and it seemed that 0.0 may be the best for treadwear according to some CL members that seemed to have a good bit of knowledge on the matter. I called a local shop and was told that setting 0.0, even was though was within specs, would cause driveability issues. I had a different shop set the front toe @ 0.0 anyway when I had new tires put on recently and driveability seems fine. I haven't had the new tires on long enough to show any abnormal wear issues though.

That's what they seem to say.

Most likely the alignment got out of whack when you got it. Could of been during the transportation of the vehicle on the cargo ship when it was comming from Japan. The cargo could of gotten banged (no the car), therefore could of made the alignment out and the same for the geometry. At the factory, the car was most likely aligned correctly before then.

I would get it done at the alignment shop that knows that they are doing. The alignment person I go to, apparently adjusts the subframe to correct the geometry of the car which balances the cambers since the camber itself isn't adjuatable.

Yes, IS-F is also experiences the similar issues. One of the tests there owners are doing there and same with the IS is trying near 0 toe or 0 toe.

What are your current camber's at? If you could adjust the subframe and balance things out, it could make it better.

In the green does not necessarily imply it is dialed in percisely for the car since green means it is within acceptable range in the specs. It can be in spec green, but on the very extreme edge of being out for instance.
