I've just switched to my lower profile summer tires (235/40r18 front and 255/35r18 rear), and have noticed that the rear end of my G35 dog tracks slightly to the right under heavy acceleration. I know that solid rear axle vehicles have the tendency to kick the rear end to the right when they break loose under heavy acceleration due to the drivetrain rotation. But my G35's dog tracking happens only under heavy acceleration, when the wheels are gripping the road. I have to correct it, by turning the steering wheel about 22 degrees to the right when the dog tracking happens. Could this be caused by a slightly incorrect thrust angle? Which rear control arms or components could cause this? Does anyone else have this problem?

2003 G35 Coupe 6mt, completely stock rear end.

 

get your car aligned. i have had bad alignments and had my car track left or right. maybe bushings? i am not sure tho someone else will prob chime in and lead you in the right direction.
