Pros & Cons of Urethane bushings and such

Hey all,

Been mulling the idea around for a while as I know my stock rubber suspension parts are slowly deteriorating. So I would like to hear the opinions of people that have done Energy Suspension and/or Prothane bushings, and what they like or disliked about them. Any added noise? Best/worst experiences, etc?

My '05 V6 convertible is my daily driver and I plan on keeping it a long time as such. Any constructive opinions would be greatly appreciated.

Urethane is stiffer, more stable and should last longer. Depending on where it is and what it is doing it may require a special grease to keep it from squeaking.

For a dd your '05's rubber should still be in great shape unless you have a ton of miles on it.

For body mounts, IMHO< I would keep the oem style units. Urethane while great for stiffening things up, in a street vehicle, it takes that unibody and increases impact forces in areas that over time (and dependent on road conditions) will be destructive (such as tearing body panels at connection points, etc.) and it's not exactly a "nice ride"...... ona longer trip, you will feel it yourself from a standpoint that it is physically tiring as compared to the less less harshness of the oem style bushings. As far as sway bar bushings, etc., sure, go for it.... it will be a bit of improved handing and you will feel the increased stability but the general NVH aspects will be comfortable

I like where this is going so far, good input.
Right now I have 113k miles on the Mustang, and the roads I drive are pretty average, for California. Not the best, but not the worst.

I was wondering about the stiffness of urethane. Like you implied, it might be great for sway bars, maybe too harsh for daily driver control arms and such, and definitely not the best choice for motor or body mounts. (Which I hadn't even considered, so thank you very much).

Keep them coming please!

I have not changed them out yet myself; but my 2010 with 95K miles is due for the control arm bushings to be replaced. I would think the bushings on the 2005 car would be pretty shot by now, even with less mileage, simply due to age.

I will go with the harder urethane bushings because my car is becoming more track oriented and I want to tighten everything up, even if it does cause some increased NVH.

If you want to maintain the OEM ride and handling, in other words do NOT want to tighten or stiffen it up, then go with the OEM bushings.

Don't worry about the body mounts, generally we are not talking about those and I never heard of anyone replacing those.
