Have my DB8 and just recently got my alignment done. Lately, the inner parts of my rear tires have been wearing out abnormally. Now, The rear end feels like it wants to swing out. when I drive in a straight line, I almost have to countersteer 75% of the time to keep it straight. Any Ideas???

 

take it someplace else and have it rechecked...might have been adjusted to wrong specs or may have come loose...either way you'd be up for free re-alignment and if you bitch enough, they should replace your tires....unless you have aftermarket suspension

 

Sounds like you need to take it back and have it rechecked.
