Engine mount pair, Density Line, Volkswagen Golf (2015-2017)
Model years: 2015-2017
034Motorsport Density Line Performance Engine / transmission mounts for the 8V / 8S Audi A3 / S3 / TT / TTS and MkVII Volkswagen Golf / GTI / R.
Density Line bearings are designed for performance and offer a perfect compromise of sportiness without sacrificing comfort. Density Line engine mounts are cavity and liquid free and are made of high hardness rubber to significantly improve performance and durability over original mounts. The Density Line motor bearings improve the driving behaviour by eliminating the slippage present in the standard bearings.
The Street Density engine bearings are made of a rubber material with a hardness of 50 to 60, which is about 25% stronger than the OEM bearings. Since the 034Motorsport Density Line bearings are also free of cavities or fully filled, this leads to a considerable reduction in the movement of the drive train compared to the OEM motor bearings.
The Density Line bearings reduce traction slip and enable more precise switching without increasing vibrations or noise in the interior. These bearings are a complete performance new development and not a simple replacement for the OE bearings.

High-strength durometer rubber vs. PU (polyurethane)
Density Line Mounts are made of rubber with high durometer hardness instead of polyurethane for various reasons.
Rubber is well suited to dealing with various forms of stress, while PU is only suitable for compressive forces. Rubber is also more suitable for absorbing transverse forces, PU is not suitable for this. This is why bearing bushes are mainly made of rubber. Rubber is also excellent in shearing where polyurethane is ineffective, making it ideal for wishbone bushings that exert a shearing force on the bearing bush during operation. While vulcanized rubber mounts are more expensive to prototype due to the increased complexity of manufacturing and high initial tooling costs, rubber is inherently better than polyurethane as a damping medium for mounts and bushings.Rubber does not wear as quickly as polyurethane, which ultimately results in a more durable component with consistent performance and comfort.
