Default 2004 WRX Wagon Motor Mounts- DD

Motor mounts are starting to go on my wagon. What mounts can I get that will be A) Stiffer and B) add minimal NVH? I have the Group N Transmission Mounts and they added a pretty decent amount of NVH. I'm mostly used to it now but people think that there are rocks in my transmission when I engine brake would prefer to not add any additional NVH if possible with the new mounts.

Stiffer means more NVH, sorry. I have the Group N motor mounts in my wagon (along with trans mounts and cross member bushings), and I notice a lot more vibration at idle. Once I'm moving, it goes away. Once I'm on the highway at a decent speed (say, 75 MPH) I can hear the engine working. I can almost hear each cylinder firing. By 80 MPH or so, it is loud.

So if you want no increase in NVH, go with stock mounts. How much extra power are you pushing? If you're only stage 2 or so, the stock mounts will probably be fine.

I'm basically stock. I have a "Stage 1" Cobb OTS flashed on the ECU and a catback. So I'm assuming you would say stick with OEM?
