Yo,


My GTUs needs new shocks, and I'm wondering if I should replace all my stock, possibly tired rubber bushings with polyurethane. I found the Energy Suspension total kit for around $115 and was wondering if anyone was using it here.

My main question is how did it effect ride quality?

My car is a street car, with an occasional autocross or track day thrown in. I don't want to rattle my teeth in my car.

Thanks for any input!

I want to KNOW too, I was thinking of these those next!

I am going all poly this winter as well, with all new suspension. Pretty sure I am going with coilovers to get the 1" drop effect w/o torching my OE springs.

 

Although I haven't done the rear control arms, I've done all the rest. Yes, I think it's made the handling at the edge more predictable.

Spend another $100 and buy a 12ton press though if you don't know someone that has one. You'll easily spend that paying a shop to do this for you. It's not that bad of a job. Toughest part was getting off the front control arm bushing (well, the rear bushing on the front controll arm-- the BIG one). It has a metal sleeve in it that I had to carefully slit. Soak in thinner all night to loosen, clamp in vise and twist like crazy.

Worth the money.

 

thats next on my car but I'm going with the mazdacomp ones. I've heard people complain about the fitting of the engery ones.

 

I have installed the bushing of the front control arm and they are real good. The suspension feels more solid. I will installed the control arm bushing this winter, tell you later how the feel.
I didn't have any problem with the installation or fitting.
