well, to be honest, what exactly are you trying to cure? if it's "stiffness", than springs. if you feel like the ride needs to be controlled better, it's shocks. more than likely, you need new springs.. but upgrading springs, you may as well get new shocks as well to control the bounce better and slow down the oscilations.

So, i bought an 01 Kia Sportage. before i even drove it, i nick-named it The Goat.. it has been just like a goat.. stubbern at every corner...
