Re: New 2004 Owner Handling Issues
6k miles seems a little early but you might want to try replacing your steering stabilizer. It's only $30 and a 5-10 minute job to do in your driveway.
SRT-6 springs will fit and are much firmer (firmer even than most "performance" aftermarket springs). You might be able to find a set by asking around or over on the Parts Classifieds forum.
