I recently replaced my lower engine torque arm bushings with Powerflex; purple in the front, yellow in the rear with the black insert installed. I will say that NVH is much more than stock. There is a small but noticeable improvement in handling. I hope that the NVH will settle down in 1k miles or so.

Anyone else have experience with these bushings?

 

I have the NM ones. It definitely makes for a bit more vibration, especially sitting at a light. It doesn’t really go away as much as you get used to it. It’s definitely worth it to get the squishy feeling on take off tightened up.

 

Yes, sitting at the light is the only place I notice it; especially with the A/C on. At highway speeds, NVH is virtually the same as stock. It definitely tightens up the chassis though.

 

Just mounted one about 2 weeks ago, no black insert, just the yellow and purple bushings. Definitely some NVH (mostly V) at a stopped idle, easy enough to mitigate.

I notice a much smoother takeoff. I just re-did a good portion of the suspension so I don't notice a lot in the handling dept. that I can directly attribute to it, but the takeoff is much better.
