Recently I had installed enregy suspension bushings on my 91 CRX Si and had noting but problems with them. They were always squeeking and making noise and some of them even split and cracked. Well I decided to take them out and give the Prothane bushings a try. Well I wanted to let everyone know these bushings are definately in my opinoin are better than the energy suspension kit. My car handels better than ever, and there are no squeeks, clunks or any noise from them. Let me know if you or anyone you know had any problems with the prothane kit. thanks.
