hey folks
would 30-40 lbs make any difference in a 335 horsepower car?

Not really. I think that's roughly 3-4hp loss.

30-40 lbs. is no big deal. I will be dynamatting the whole rear section of the car. Hatch, wheel wells, everything seats back. I think this will make a significant difference in road noise and give the car a better audible environment.

if you get a chance i'd be interested in reading about the results of your efforts.
seems i hear a fair amount of wheel noise in the front wheel wells also.

anyway good luck, all the best

I would also like to read about the results of your noise reduction efforts. I just purchased my Z and the only drawback is the cabin noise. An audio dealer I trust resommended installing Dynamat Xtreme in the door panels. Any comments about this idea...? What ios the best method to insulate the wheel wells?
