The EP6577 bushing is a full replacement bushing as where the EP6579 simply replaces the stock insert in the factory bushing. The inserts work to reduce motion, but the basic issue of the OEM bushing remains, it is hydraulically damped and can potentially fail on track.
So if you track your car then you may want to upgrade, but if it's just a street car then I would stick with what you have.
Feel free to call, PM or email me anytime with questions.
