I have a diff brace and open exhaust, so my car is not exactly plush and refined anyway. My main concern is interior vibration---years ago I had an engine torque brace and hated the cabin vibration.

Informed firsthand comments appreciated

 

Rich,
I have no issues with mine. I didn't notice any additional cabin vibration over what I already had with stiffer mounts and the diff brace and you definately get a more solid feel from the shifter. Money well spent in my opinion.

hmm.... well if you hated the engine brace u might not like it.... mines kinda noisey at certain rpms, altho at others its fine.... i'd say its liveable based on the other mods you have
