I noticed yesterday that the O-ring looking gromet that sits between the spring and strut mount is shot to hell and torn pretty bad. So I'd figure id replace it with a polyurethance one then figured while im gonna have the suspension torn apart might as well get rid of all the rubber pieces. Im looking at getting the Energy Suspension Master bushing kit. Looks like the kit includes the front/rear control arm bushings, front/rear strut bushings, and bushings for the shifter. Questions are, was it hard to install? and did you notice a good difference in handling? Any info would be appreciated. Thanks
