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.

Not sure if those are rubber. I would call Ford and see what they want for them. Hopefully someone else can chime in here with some more help.

Metal to metal contact (on something that can move) is not a good idea, IMO.

But some run without them and give no complaints.

Those look like the Polyurethane ones....maybe they dont make the rubber ones for it anymore?

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.

Run isolators. Like said above, metal on metal is not good. I replaced my clapped out rubber ones with poly rears and poly fronts. I bought mine through Maximum Motorsports and they are made by prothane. You can get them from Energy Suspension as well.

You can still get new rubber ones from the Dealer pretty cheap.

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.

you can reuse your stock ones if they are in good shape. Thats what I used when I swapped out mine.

rigamaroles · Aug 16, 2006

I just reused mine, I have no complaints whatsoever. I've driven a lot of lowered cars and mine handles great and has a decent ride quality. You can check out the stance from the pics in my sig.

If anyone wants them, I have the front bottom coil spring isolator in poly that I did not use. It is a tube basically that wraps around the spring where it sits in the spring cup. I'll give them to someone if they pay the shipping, probably 3.00 or so.

Mustangs Unlimited sells the rubber insulators.

If i'm reading that correctly, they are all sold individually in that link, and by the time you buy 8 total insulators, the price is pretty high.
