Definitely a different design than most others but looks pretty straight forward. Looking forward to any tips.
I just installed both the 55 duro (street) cpe passenger side and driver side mounts this past weekend with
@parallax . Install was pretty straightforward granted you have the right tools. I had an engine support bar above and jack on bottom to help align the engine/transmission. Also the passenger side mount makes it impossible to fit a socket to torque or tightened the body side bolt screws, so you will need a 16mm crow's foot to get in there.
As for the driving impressions, the engine/transmission feel much more connected to the wheels. It's an instantaneous response of power when you press the accelerator. Wheel hop is gone, all I get is tire spin when I'm mashing on the gas.
NVH, the car is definitely louder when the engine is under load or first starting up. It's similar to the soundaktor (i've had mines off since I bought the car). It's totally liveable and if you keep the revs below 2500rpm, there's no difference between a stock car and these mounts. I will have to say, decelerating from 3500rpm to 2500rpm in sport mode brings out this loud buzz and it's the only thing that could be bothersome for passengers.
I'll try to get more seat time in. I've only driven 20 miles on them so I haven't had a chance to really get things settled in. Keep in mind I have a stage 1 bfi dogbone insert and a catted downpipe with stock catback that also plays into NVH.
