What would be the difference in using polyurtherne bushings vs aluminum bushings?

 

your the race car driver and you don't know this?

 

I'm guessing aluminum is almost unbreakable but noisey as hell

 

well I dont know everything.

 

yea. I was thinking a rough ride though since the polyurthene would give a little more than the aluminum. It is another step up from the rubber bushings. A much stiffer ride. Probably not for the street I would think.

anybody else?
