Most exterior noises come from the road and your moving tires. Lowering your suspensions or having low profile tires only makes it worse. Not forgetting, as tires wear out, the noise gets louder. To overcome that, you will need a noise barrier to block out the sound coming into your car from the floor pan and most importantly wheel wells.
Good workmanship is hard to find these days and installing the materials correctly is the key to having best results. You can do it yourself but without the proper tools and technique you may not get the best results.
As you need to take out the seats, carpet and wheels for these installation, it's better to leave it to the experts.
Below are some pictures of how the floor pan and wheel wells are covered with Luxury Liner Pro on a noisy MPV. An installation done by Robin Audio Technik, one of our reliable and experienced installers.
(Note that the floor pan was already installed with another brand of Butyl Rubber to only stop vibrations.)
