AGENT 99

Yep, yesterday I was sitting on the ground next to my car's front wheel just talking to it and I started to wonder when I should replace the bushings that hold the front top arm thing? You know, the thing skunk2 makes to fix your front alignment? Well that arm. And all the other ones in there? Would it make a signifigant improvement to replace these with aftermarket ones? Sorry I cant remember part names right now, its 6am. And would after market ones be squeaky or harsh?
