Result ?? Huge difference in the interior decibel rating reduction. I could now drive the car with windows down at 90mph + and speak to a passenger with a non-strained voice.
Penalty= about 9lbs. But I could shave that with CF parts no problem. 
I actually have a Decibel meter and will attempt some 'before & after' testing when I do the same to my Z4 coupe.(maybe this Winter). |
I don't think anyone should worry about adding 9 lbs of weight to their car. Better that the driver should lose weight if you want better performance from your car...and your body.
