034Motorsport Density Line Street Density Engine and Transmission Mount Pair for Audi A3, S3, TT, Volkswagen Golf R, and GTI (2015–2024)

For MQB-platform Audi and Volkswagen models, the 034Motorsport Street Density mount set pairs one engine mount and one transmission mount that replace both factory drivetrain mounts on 2015–2024 Audi A3, S3, TT, Volkswagen Golf R, and GTI. The mounts use 50 durometer and 60 durometer rubber, which 034Motorsport rates at roughly 25 percent stiffer than stock. Both mounts are void-free and solid-filled, so drivetrain movement drops well below what the factory mounts allow. The result is less slop, crisper shifting, and reduced wheel hop, and the maker reports no significant increase in noise, vibration, or harshness in the cabin. These are complete, re-engineered mounts rather than inserts pressed into factory mount bodies. The set is made in the United States.

034Motorsport parts sold by PMB Performance carry a 24-month warranty.

034Motorsport developed this pair for the 8V and 8S Audi A3, S3, and TT and the MkVII Volkswagen Golf platform. On these transverse cars the engine mount sits on one side of the engine bay and the transmission mount on the other, and together they carry the full weight of the drivetrain. Because the pair is sold together, both ends of the engine change rate at the same time, which keeps the drivetrain from pivoting around one soft mount. The Street Density pair is fluid-free, so there is no hydraulic chamber to leak with age. 034Motorsport builds and tests its drivetrain mounts at its Performance Facility in Fremont, California, alongside its tuning department.
