I bought two SEs prevously that had this exact same problem... one worse than the other, so bad in fact, that it looked like the car had been in an accident LOL. It appeared that the plastic wheel hub wasn't molded properly, causing the misallignment. Anyhow, I returned them both for an exchange.
'Course exchanging things at RatShack is harder than pulling one's own teeth with a pair of vice-grips, had to jump thru hoops both times with the bonehead store manager to get him to exchange them <aarrgghh>.
P.S. (don't wanna get on a rant here, as it's quite easy for me to do when dealing with RS), but BOTH of these cars had NEVER touched the ground when I returned them (one, I hadn't even assembled yet). Yet, the store manager always seems to try to either:
A) Claim "that's how they're manufactured", or
B) Infer that it's something that you've done to the product.
