Hi guys, anyone done any particular sound proofing or insulation to their 3IS? Will be picking up my car from the dealership next week, would like to know whether it is necessary to do sound insulation for the car and if yes, what product you used? Thanks.

 

Car is by far the quietest I've owned(when I'm not in sport+ and its floored) However a very noticeable improvement is the tires especially with the Fsport, the stocks are very noisy. Swap them with Pilot super sports and you'll get not only get a road noise improvement but all around handling as well.
