Since the 1990’s the Nissan Skyline R35 GT-R has been regarded as one of the best sports cars on the market. The popularity of the Nissan Skyline is a result of high in performance (aka powerful) and tech.
However, even left at stock, the Nissan Skyline has a loud interior cabin. Vibrations from the engine, exhaust, road and tires all contribute to a loud interior. As discussed in the following forum, Nissan Skyline owners are looking for automotive sound deadening options to install in their Nissan Skyline’s to quiet interior noise: Reduce interior cabin noise of a Nissan Skyline. The good news is that you can find a range of premium automotive sound deadening products at B-Quiet.com that will reduce vibrations and noise in your Nissan Skyline.
B-Quiet Ultimate Automotive Sound Deadener
The team at B-Quiet recommends installing Ultimate Automotive Sound Deadener under the floor pad, on the doors and panels, and in the trunk of your Nissan Skyline.
B-Quiet Ultimate can be applied to the floor, by removing the carpet and the seats (front and rear) and applying the peel and stick sound dampening material directly onto all metal surfaces. This process is simple and would take a handy person about 3-4 hours.
B-Quiet Ultimate can also be applied to the door panels and in the trunk. You simply remove the interior panels and apply B-Quiet Ultimate inside the door skin and in the trunk.
B-Quiet Ultimate is not too expensive, or heavy, but will dramatically reduce vibrations and noise inside the cabin of your Nissan Skyline.
Why Sound Deadening Matters for the GT-R
The Nissan GT-R is built for performance, not luxury. Wide 20-inch tires transmit constant road roar, while the dual-clutch gearbox and driveline send vibration through the tunnel. Add a performance exhaust, and the trunk becomes an echo chamber.
By applying 100–110 sq ft of sound deadening, you can lower cabin noise in a 50% reduction in perceived loudness. Better yet, your upgraded audio system will sound tighter and clearer without rattles or distortion. For enthusiasts, this strikes the perfect balance: street comfort without sacrificing track-day performance.
