While lying under my Z to change the oil, I noticed that the ****ing idiot alignment tech(???) at the dealership put my front wheels on backwards. I have been driving for 1300 mi with my right front wheel on the left, and vice-versa. Shame on me for not noticing that the rotation arrows were not going in the right direction when I had the work done, but I was completely consumed with the fact that the jerk had not aligned the car to spec (whatever that is). FORWARNED IS FORARMED!!! Don't assume that the idiot that checks your alignment, will put your wheels back on the way they came off.
