driver's side lower
 

the driver's side of my 03S is about 1/2 inch lower than the passenger side. What is the probable problem? Is this a warranty issue? tire psi is correct.

How long have you owned this car? Possibly the prior owner was tracking the car, and had this specific set-up for racing. :eek:

How much do you weigh?

just kidding...

hope it is nothing expensive.

I'd find an independent shop that does alignments, and have them check it out. You might have to have them do what's called a Corner Balance, which tweaks the suspension so that weight is evenly distributed between the wheels.

It's possible someone DID set it up with a little bit of a left lean, for track duty.

A good shop can balance it perfectly, and could even do so to compensate for your weight in the driver's seat.
