I just noticed this problem on my way to work as I was taking an on ramp to another freeway slower than usual but going 60mph on the turn. My car felt like it was wobbling. I had just gotten new tires as well as a Spl rear camber kit. My alignment specs came out okay so I was thinking it could've been the v12's? They only have like 250 miles on them. I'm goin to try replicating the problem again once I get off and see how it goes.

Interesting... My car does this slightly, but usually in parking lots and the steering wheel almost turned full lock. Its still pretty cold here so I though it was the tires skipping a tad due to no front grip. I guess I should go to the dealer.

(My car has 700 miles on it and I noticed this the first day I bought it)

This is normal, especially when cold.

May be the tires... If you can jack it up it shouldn't be hard to just double check the bolts are tight though. If they feel loose you may want to get an alignment check. The problem in my case could be demonstrated with the help of a pry bar. A little force would make it obvious that the stock adjustment bolt was loose.

Sig did you ever figure out what the issue was? Mine ended up being a really busted rear diff mount.

Sure did. Solution on p2. :) The stock camber adjustment bolt came loose and was allowing the left rear camber to change randomly.

Ha well I guess more than one cause for a similar symptom. Glad you got it figured out man.
