Purpose and function in the vehicle

The presented sound insulation is part of the Carpets, floor mats, trunk trays category and has been designed specifically for the rear floor area of the BMW E87. Its task is to reduce noise transmitted from the suspension, wheels, and luggage compartment into the passenger cabin, as well as to limit floor panel resonances.

Its placement in the rear of the vehicle allows for:

• reduced noise levels at higher speeds,
• limitation of vibrations from the rear axle,
• more uniform distribution of soundproofing layers throughout the cabin.

Construction and acoustic fit

The insulation is factory-profiled to the geometry of the BMW E87 floor, which allows for precise installation without the need for cutting or modification. The appropriately selected density and material structure promote effective vibration damping and sound absorption in the frequency range typical for suspension operation and tire rolling.

Key functional features:

• shape matched to factory floor stampings,
• possibility of installation in existing carpet mounting points,
• compatibility with the original trunk trim and rear seat.

Benefits of using original sound insulation

Using original sound insulation in the rear floor area allows you to restore the factory level of acoustic comfort, which is especially noticeable when driving on roads with poorer surfaces. A properly selected soundproofing layer:

• improves travel comfort for rear-seat passengers,
• limits noise penetration from the luggage compartment,
• supports stable positioning of the floor carpet.

For users who value consistency with the factory BMW specification, using an original component is more beneficial than installing universal mats, which often require compromises in fitment.

Characteristics of the used component

The offered sound insulation comes from dismantling and is a used product, which allows maintaining the original specification while reducing costs. This type of solution is particularly attractive for comprehensive interior renovation work, where maintaining compliance with the factory construction and materials is a priority.
