Do front spring insulators have any influence on comfort?
There are several types, stock soft one or hard poly one.
I want to go for a softer one if they make any difference.

 

Most people either use the OE rubber or remove the insulator altogether.

Can I just remove them? Doesn't it make any noise or make it harsher?

 

The stock ones are jus for noise insulation. You can take them out and probanly wont notoce anything different

 

how did you got around this dilema? what else did you changed on the suspension?
I went thru some major updates for the front and rear and decided to go with the moog stock (I think) replacement. I doubt any dampening happens thru the compressed thickness of this insulator. some ppl wrap the last coil in electrical tape.
no insulator may transmit some noise, I doubt u'll notice any comfort difference
also, stock spring had a round section at the end where it goes onto the insulator into the k member cup, my prokits were ground flat. I think the insulator may help conform these two shapes one agtainst the other (not that it can really go anywhere with or w/o a sure footing)

 

I have ground control weight jacks and they say not to use an isolator. The weight jacks wouldn't work with an isolator anyway. I can vouch that it's not as bad as you might think without isolators. but its hard for me to tell what made the difference since i upgraded everything at once.

If i had used just regular springs like eibach, moog, or whatever i would use an isolator but i would probably have done the hose slid over the end coil, but OEM rubber would be good too. I can't see any reason to use the harder poly in this application.
