This question piggybacks on my earlier thread about lowering and suspension. Andy - stated that he preferred no bushings in the rear, but we can't get away without them in the front. I have read not only here but other places that polyU is not forgiving enough. So why do so many people use the Energy Suspension PolyU Bushings? Which is better?

If you are going to rebush aren't the poly bushings all that is available? I know you can buy new A arms from Corvette Recycling that have the original rubber bushings, but that is a bit expensive.

With the engine out is absolutely the best time to rebush, especially the dang lower rear a arm bolt.

I hate poly for the rear. Just don't do it. I have outlined why in your other thread.

Andy, I love the Banski system and that is definitely in the plan for the future. I just have a limited budget and motor and trans are first priority.

I just found out that no rubber is available unless you purchase the whole dog bone or component whatever it may be. And that may not be available either. So if replacements must be made its almost definite that poly or delrin will need to be used.

I would just leave it alone until you have the funds to do it right, that is unless the rubber is really shot.

Poly can work ok if you make sure the bushings fit correctly, but this may require either shaving the bushings down or grinding the width down on some of your suspension links. Basically poly is very firm and only wants to pivot on 1 axis. The rear end requires it to pivot on two axis to an extent. The biggest problem area is on the lower camber rods. So yeah, poly is better than nothing but will give you less compliance IMO and a harsher ride.

I used poly in the front. As you will probably find out, there are not many options. On mine the top has no droop. I had to put more force on it than should have been required. The bottom turned out fine. I have to agree on Banski for the rear. I have to cross a few RR tracks when I go into town, and it is very smooth.

Ideally, Corvette recycling's A arms are bought for their ball joints to save labor, new joints end up the same. and meanwhile you throw the new bushing's in.

are you saying the poly's for the front a acceptable.

to save a great deal of money, how do you know if the ball joints are still good, 140k miles on them and they don't movement when the wheel is up from jacking.

but to take it all apart and not do them is kinda stupid too...this would include the tie rod ends, but they are all tight.

is the poly steering rack bushing effective? I do have a new rack....

For the front there is also Delalum from Global West
They use Delrin and aluminum. Many love them. Not cheap, but unless you go spherical rod ends, there really isnt much in between.

gulstrand has roller bearings

I don't like mine. The front end is very harsh compared to the rear. With that it depends on what you plans on what you are doing with the car. I believe my problem is with the upper. I even have them as loose as they would go.
