I agree with Moses - if you're willing to take the time to properly maintain poly bushings and the increased stiffness is desirable, it's a worthwhile upgrade. My experience with them has been in muscle cars (I've owned a couple Mustangs and worked on several F-body camaros/firebirds) and I was happy with them.
