What do u think this setup for street:

rear suspension all rubber and front all polyurethane (except tension bushing)..

Please advise..

I'm not sure why you'd want to do this, or what you result you expect from such a mix. In my experience, it's not normally a good idea to have components that are "tighter" or "higher performance" on the front than on the rear. Tends to make a car wander and the rear end feel "loose". Definitely happens with higher performance tires on the front than on the rear, and also with suspension components. So I personally would not recommend this setup.

thank you Arne..have done full polyurethane bushing and how was it?
