welcome for the link
a few things i did to my old taurusaurus were to add new motor mounts, added monroe heavy duty struts (sho)and hr speed rated tires
i was less of a car dude than i am now and im not a car guy at all still really but those changes made quite a difference in responsiveness and highway driving....its almost amazing how those things translate to power to the road
and i didn't even know about filter, exhaust and intake mods when i had it...not that there were many if any...if it didn't get to the point of being too old i'd still be driving it and putting the smack down in the taurusaurus
