Road Noise

Body and Interior

Vehicle Information: Year: 1990; Body Type: Coupe; Total Mileage: 56000;

According to Road & Track, up to 50% of the noise in the passenger compartment comes from the tires. I noticed a major reduction in road noise when I put new Bridgestone Potenza SO3 tires on my 1990 C2 coupe (I know - they are not a Porsche approved tire but I like them). I also had the doors lined with Dynamat sound insulation as part of a mild sound system upgrade. A friend noticed a similar reduction in noise levels when he put Pirelli P Zeros on his 1988 911 coupe.
