What is the problem? Sounds coming from the exhaust and the rolling of the tires come through the bottom plate of the boot. The relatively light steel, especially where the spare wheel is located, is set in motion and audible in the vehicle. The boot is connected to the wheel arches and is therefore insulated with the same product.
What is the solution Insulating the boot floor is fairly easy; equipped with anti-drumming mats of the heaviest type as much as possible. Degrease and clean the surface thoroughly and apply Vibraflex Extreme or STP Aero Bomb, as much as possible. For extra insulation, provide the boot with a new insulating mat, the Isomat VM, a floor mat that both dresses up the interior and provides extra insulation.
You therefore apply these products to the floor of the boot and in particular the pit where the spare wheel is located. All these materials are mounted inside the vehicle, not on the outside! All anti-drumming products are self-adhesive and can be cut to size with scissors or hobby knife. The Isomat VM is not self-adhesive.
