Before you go order up a bunch od urethane bushings, you need to decide what YOU want. Do you want the car to ride nice and soft like stock? Do you want it to handle some better with some harshness to the ride quality? If you don't mind giving up a little of that stock smoothness, you might be happy with the urethane. They certainly last a long time. They do have drawbacks. They transfer more road vibration and they tend to squeak. It's tough to get them to stop, too. At least permanently.
I did suspension and alignment work for a living. I have never preferred any of those "pre fabbed" kits you can buy. They are convenient......but for whom exactly? I would rather pick my own parts out individually and get exactly what "I" want, instead of what someone else picks out. That way, I can get the best. Moog. When you buy in kit form, you don't know what brand you might be getting. Just because you're buying from say, "PST" doesn't necessarily mean that's who makes the parts. In all liklihood, it's not. Remember, that's your front suspension you're buying parts for. I don't think you want inferior or unknown parts there.
