I installed the AWR motor mounts today. I had Tony from AWR get some "custom" softer inserts for the mounts, 62 durometer instead of their normal 70, 88, or 95 duromater options.
They're a good deal heavier than stock because they're made of steel. They won't break when you launch it or sky it off curbs
The install was straight forward. The only real special torque spec you need is the 50 ft-lbs for the cross bolt through the mount. The rest of the hardware just gets torqued to OEM spec (~28 ft-lbs works for the 6 bolts and two nuts)
NVH isn't bad. Definitely noticeable vibration at idle and there's a good bit of "tingle" in the pedals at lower RPM cruising (like when the cluster aggressively tells you to upshift to 6th at 30 mph...) and the wheel and seat have a bit of a constant vibration. Highway cruising isn't a noticeable difference from stock. When on the throttle hard or higher in the revs it just feels like the engine is more solidly connected to the car and any vibration is high frequency and not really in your face. Absolutely no new noises or anything like that. I've had a wide range of mounts on my prior cars from literally solid aluminum mounts to soft STI Group N mounts so I feel like I have a decent level of experience with different mounts and these are solidly in the middle of my experiences.
Now for how they perform... Damn
If you've ever launched an ND at autocross/drag strip/whatever or even on the street you'd know how horrible the wheel hop is. I did diff mount inserts when I installed my OS Giken LSD and it helped a LOT, but man... Holy **** it launches soooo smoothly now! I have never had a car launch like this, just chirp and bit of spin and tracks dead straight. Really fun! On top of the silly launching difference, the way it behaves on throttle transients is massively improved. Less flopping about and it just feels super direct. I love how responsive it feels.
I've had the AWR uppers for a while and Tony whipped up a custom one for me to clear my silly header, great customer service
