Wasn't there some talk from Karma Automotive last year about a noise & vibration upgrade package/procedures? Did that ever come to fruition? Did anybody do it?
What does this kit do? I haven't noticed any issues with mine.Karma News answered on the NVH kit:
NVH kit is currently available at Karma authorized service providers. If you are interested, please contact them and inquire about TSB # 03.01.15.0001.06
Please note, this kit is not covered under vehicle warranty. We would recommend taking your car to your service provider who would be able to walk you through the options available to you.
I want to bring this up again.In the original post, Karma News described as sound deadening, and vibration reduction. I asked if it was "user" installable? The reply was it takes nearly 8 hours to install the "package" by a CSP.
Other than ICE noises, I don't find noise or vibrations in my Karma. That's not to say it couldn't be better -- but it certainly is not objectionable. Some time ago, I installed vibration damping material around the rear speaker panel to keep it from vibrating against the rear window. I also added some foam in side the door molding to reduce wind noise somewhat. Pretty satisfied, but sound deadening from the ICE and muffler would be desirable.
I will defer to Harley Guy and Philly Fisker for details.
