Does the 3rd gen IS have camber on the front and rear tires? When i look at my car from the back the rear wheels seem to be slanted slightly inwards. Ive also heard it only has it on the front, not sure which is true.

 

Yes, the IS has factory camber for both front and rear. I believe they are also adjustable from what I have read in the forums. If tire wear is a concern, you can always change out the front LCA bushings for RCF/GSF LCA bushings. They are easy to do on your car and it does make it seem a bit more stable and responsive instead of the boat response you get from stock.
