Steeda heavy duty engine mounts - yes or no?

Hi everyone, I hope you are all doing great.

I have a set of Steeda heavy duty engine mounts (https://www.steeda.com/steeda-mustang-engine-mounts-555-4005.html) ready to be installed, however I'm not sure installing them will be the right thing.

I could not find enough useful information if they will do more harm than good. I read that they will transfer more vibrations and nvh to the inside of the car, especially during idle.

The Mustang in question is a street car with a mild suspension build (eibach/bilstein springs and shocks, eibach roll-bars, gt500 front and rear control arms etc). It does not see track time. However it is driven hard on weekends in specific driving roads.

Do you think there are any gains to be made when installing the Steeda engine mounts on this car? is there any chance to even notice the improvement on the street, or is it absolutely unnecessary for this type of car/driving? How bad are the vibrations from your experience, using the softer red bushing?

Thanks in advance.

Unnecessary for what you're doing and all you'll gain is noise and a possible new headache. These red mounts are known to degrade badly and deform from engine heat. Do a search and you'll find some other threads on them. BMR mounts are kind of the go to around here, but also likely unnecessary if you're not going to the track.

My Steeda mounts have degraded. There's not really a reason to use them if you're sticking to the streets. There's probably not much reason for amateur track days either unless you're competing...but when has that ever stopped me?

What difference did you notice after installing them?

Increased NVH. Not a whole lot but I'm running spherical ends on everything so hard to say what difference it makes. Didn't make any noticeable difference in anything else.
 
I have the Steeda mounts with the red bushings installed for about a year now on a 2008 Mustang GT. I did notice a small increase in NVH, but also noticed a nice improvement in the shifter. I had already installed the MGW shifter a couple of years ago, so the motor mount improving the shifter feel was an unexpected benefit
