its not downgrading, its about driveability. everyone seems to think stock parts are crap. thing is unless you race, autocross, drag, the fact is you really don't need to change out parts unless its about show and go. My stang is a daily driver so sometimes its a pain to continue to maintenance all my aftermarket parts.
I have had them on for about 18,000 miles. I usually re-grease them every 8,000. I noticed after I changed rims and tires the last time the squeaking subsided a lot.
