It depends on your preference and tolerances really. Polyurethane isolators are great quality and stiffer than rubber but don't settle at all. They may leave your car sitting higher than anticipated. Rubber isolators will work fine and will usually settle in a little dropping your car a tiny bit. Not many people run with no isolators, but some do run a combination of using the upper isolators and leaving the lower isolators out or vise versa. Some people report some added noise and vibration, but it seems like it doesn't make that much difference.

Depending on what your car has gone through it will have it's own unique situation. I recommend rubber isolators as they are a good "in between" option. You can always take them out if you don't like them.

ok where can i buy the rubber ones at? all i can find is the Polyurethane??
 
I've had it every possible way, and without a doubt, the energy suspension isolator kit left me with the best ride quality.

None at all, is just plain not smart, potholes feel like they are 3 feet deep.

Rubber ones were ok, but mine were destroyed.

I will say that the ES versions, may lift the car, a slight bit, but it's worth the trade off.

With NIB springs and isolators, your car will probably sit high for the first few weeks, so don't panic, it will settle.
 
I run the polys with my Eibach Sportlines. My car sits at abou 1.5" drop with the iso's (as apposed to the 1.7-2.0 advertised drop). Been on em for over two years now and they look brand new. They do give you a little harsher ride than the rubber ones do, but you get better responce out of them.
 
Place to get Ford OEM parts a lot cheaper than the dealer...

Tell Torrie that Ralph said hello for a special discount.

I have OEM on my 84 and poly on my 89. I can find no "higher" or "lower" stance due to the composition of the isolator. Of course, they utilize different springs, weigh differently, vert is heavier, so the comparison is bunk. I will say that the rubber is a lot more expensive than the poly.
