superpro vs powerflex full kit?
superpro make 2 different kits, do you know wich different?
I will have to buy also 2 Rear Wheel Bearing?

Both use the same type of material. Just pick one based on price and availability.

I agree one of these kits is a better choice over stock even if the car only sees the street.

I recently did SuperPro bushings and really like them. My car is setup for mild track use and street use.

Is there a specific place where the noise originates? front, rear?
What does the noise sound like?

The sound looks like rubber friction,
came most from rear, but a bit also from the front.
Bushes are new in front and rear.
will it short the bush life?

I get a little of that from my rear poly sway bar bushings which bind slightly. Unbolt the sway bar links on both sides and rotate the bar up down to check those.

I would add more "grease" or whatever that white stuff is called - lubricant? It is important to add lots of grease to the internal steel sleeve so that it pivots/rotates easily. Also add some to the external surface where it mates with the brackets on the body. I think grease used for polyurethane is different from standard grease so if you ran out of the white stuff included in the bushings, find grease designed for use with polyurethane.


Install note:

Also, I believe that you are supposed to have the suspension arms at the level they would normally be when the wheels are mounted and the car is on the ground. Same with the sway bar end links.

When installing suspension arms, I typically jack up the suspension assembly (w/o wheel mounted) to the approximate level that they would be when on the ground. Then I tighten and torque the bolts in that position.
