does anyone have any experience with either the Cusco engine/tranny mount and;/or the STI engine/tranny mounts? how much stiffer are they and how much is vibration and noise increased? thanks

Not so much the noise, but you will get more vibrations. They are suttle and will give you a nice back massage and transfer more HP to the wheels :)

ok cool... are these the cusco mounts or the STi mounts that you are talking about? thanks dude

Imprezer on Cusco mounts (www.i-club.com/forums/showthread.php?s=&postid=8950#post8950). Found his old post using Search, keywords 'cusco AND mount'.

My experience with the STi mounts is that it is noticeable the first time you fire up the engine. There is more NVH (http://www.nvhmaterials.com/) transmitted through the chassis with the stiffer mounts but it's not objectionable, IMO.

I have the STi ones and what I noticed besides the NVH (which I like by the way), is that you feel more connected to the engine. Response seems quicker because the engine doesn't torque with the stock sponge mounts before moving the car. Accelerations feels more direct.

One of the top five first mods I would do.

Tires
Shortshifter/bushings
Steering rack bushings
motor/tranny mounts
IC hoses
